+# <small>nlohmann::basic_json_view::</small>dump
+
+```cpp
+string_t dump(const int indent = -1,
+              const char indent_char = ' ',
+              const bool ensure_ascii = false,
+              const number_format numbers = number_format::shortest) const;
+```
+
+Serializes this value (and its subtree) directly from the flat index, without ever building a `BasicJsonType` value
+first. With the default `#!cpp numbers == number_format::shortest`, the result is the same string
+[`BasicJsonType::dump`](../basic_json/dump.md) would produce for the value
+[`BasicJsonType::parse()`](../basic_json/parse.md) builds from the same source text, called with the same `indent`,
+`indent_char`, and `ensure_ascii` -- except that members of an object appear in document order rather than sorted by
+key, and *every* occurrence of a repeated key is written rather than only the last one (see
+[Notes on duplicate keys](operator[].md#notes)). For a `json_view` (whose `BasicJsonType` is not ordered), this means
+`dump()` can print an object's members in a different order than [`materialize()`](materialize.md)`.dump()` of the
+same subtree.
+
+## Parameters
+
+`indent` (in)
+:   If `indent` is nonnegative, array elements and object members are pretty-printed with that indent level. An
+    indent level of `0` only inserts newlines. `-1` (the default) selects the most compact representation.
+
+`indent_char` (in)
+:   The character used for indentation if `indent` is greater than `0`. The default is ` ` (space).
+
+`ensure_ascii` (in)
+:   If `ensure_ascii` is `#!cpp true`, all non-ASCII characters in the output are escaped with `\uXXXX` sequences, and
+    the result consists of ASCII characters only.
+
+`numbers` (in)
+:   how to write numbers, see [`number_format`](number_format.md): `shortest` (the default) writes them the way
+    [`BasicJsonType::dump`](../basic_json/dump.md) would; `source` copies every number exactly as it appears in the
+    source text.
+
+## Return value
+
+string containing the serialization of this value, or `#!cpp "<discarded>"` if the view is
+[discarded](is_discarded.md).
+
+## Exception safety
+
+Strong exception safety: if an exception is thrown, there are no changes to the view or the document it refers to.
+
+## Exceptions
+
+May throw `#!cpp std::bad_alloc` if allocating the output string fails. Unlike
+[`BasicJsonType::dump`](../basic_json/dump.md), there is no `error_handler` parameter and no
+[`type_error.316`](../../home/exceptions.md#jsonexceptiontype_error316): the view only ever holds text the parser
+already validated as UTF-8, so there is nothing to replace or ignore.
+
+## Complexity
+
+Linear in the size of the output text.
+
+## Notes
+
+The walk over the subtree is iterative, so the nesting depth it can write is limited by available memory only, not by
+the call stack -- as for [`materialize()`](materialize.md).
+
+Strings are escaped by the same rules as [`BasicJsonType::dump`](../basic_json/dump.md). With
+`#!cpp numbers == number_format::shortest`, floats are written with the library's shortest round-trip conversion,
+exactly as [`BasicJsonType::dump`](../basic_json/dump.md) would (e.g. `#!cpp 1.5`, `#!cpp 100.0`, `#!cpp 1e+100`), and
+integers are copied from the source text -- already canonical in JSON, so this matches their shortest form too --
+except that `#!cpp -0` is written as `#!cpp 0`, the way [`BasicJsonType::parse()`](../basic_json/parse.md) reads it.
+`#!cpp number_format::source` copies every number exactly as written in the source text instead, with no exception
+for `#!cpp -0` -- `#!cpp 1.50`, `#!cpp 1E2`, `#!cpp -0.0`, `#!cpp -0`, or all digits of an integer literal with more
+digits than any number type holds (such a literal is itself classified as a float, see
+[What is different](../../features/json_view.md#what-is-different)) -- something `BasicJsonType` cannot do, since
+parsing already reduces every number to its parsed value.
+
+## Examples
+
+??? example
+
+    The example below forwards a single record out of a larger batch, and re-serializes a configuration file, both
+    without ever building a `BasicJsonType` value for the surrounding array or for the parts of it that were not
+    needed. It also shows that [`materialize()`](materialize.md)`.dump()` of the configuration sorts its keys, where
+    `dump()` on the view keeps the order they appear in the source text.
+
+    ```cpp
+    --8<-- "examples/basic_json_view__dump.cpp"
+    ```
+
+    Output:
+
+    ```json

+:   integers are copied from the source text -- already canonical in JSON -- except that `#!cpp -0` becomes

+## Examples

+
+Not available when [`JSON_NO_IO`](../macros/json_no_io.md) is defined.
+
+Serializes the given view `v` to the output stream `o`, using [`dump`](dump.md) -- exactly as
+`#!cpp operator<<(std::ostream&, const basic_json&)` does for a `basic_json` value.
+
+- The indentation of the output can be controlled with the member variable `width` of the output stream `o`. For
+  instance, using the manipulator `std::setw(4)` on `o` sets the indentation level to `4`, and the serialization
+  result is the same as calling `#!cpp v.dump(4)`. A `width` of `0` or less (the default) selects the most compact
+  representation, as `#!cpp v.dump(-1)` does.
+- The indentation character can be controlled with the member variable `fill` of the output stream `o`. For instance,
+  the manipulator `std::setfill('\t')` sets indentation to use a tab character rather than the default space
+  character.
+- As for `basic_json`, `o`'s `width` is reset to `0` after this call, whether or not it was greater than `0` before.
+
+Numbers are always written as `#!cpp v.dump()` writes them by default, i.e. as with
+[`number_format::shortest`](number_format.md); there is no way to select `#!cpp number_format::source` through the
+stream.
+
+## Parameters

+
+`v` (in)
+:   view to serialize
+
+## Return value
+
+the stream `o`
+
+## Exceptions
+
+May throw `#!cpp std::bad_alloc`, propagated from [`dump`](dump.md#exceptions). Unlike
+`#!cpp operator<<(std::ostream&, const basic_json&)`, there is no UTF-8 decoding step that could throw
+[`type_error.316`](../../home/exceptions.md#jsonexceptiontype_error316), and no `error_handler` to choose between --
+see the [Exceptions](dump.md#exceptions) of `dump`.
+
+## Complexity
+
+Linear, as [`dump`](dump.md#complexity).
+
+## Examples
+
+??? example
+
+    The example below writes one record out of a larger batch straight to a log stream -- compact for a one-line
+    entry, and pretty-printed with `std::setw`/`std::setfill` for a readable dump -- without ever building a

 Both results are only valid as long as the view -- and, for a string with no escapes, the borrowed source text -- is.
 
+## Writing a view back

+[`dump()`](../api/basic_json_view/dump.md) serializes a view directly from the flat index, without ever building a
+`basic_json` value. An object's members are written in document order, not sorted by key, and *every* occurrence of a
+repeated key is written, not only the last one -- the same two ways [iteration](#what-is-different) already differs
+from a [`materialize()`](../api/basic_json_view/materialize.md)d value, see above. `#!cpp materialize().dump()` gives
+a different result in both respects for a `json_view`.
+
+By default, numbers are written the way [`basic_json::dump()`](../api/basic_json/dump.md) would.
+[`number_format::source`](../api/basic_json_view/number_format.md) instead copies every number exactly as it was
+written in the source text -- a price like `#!cpp 19.90`, a long order or account ID with more digits than any number
+type holds, or a high-precision coordinate -- something `basic_json` cannot do at all, since parsing already reduces
+a number to its parsed `#!cpp double`/`#!cpp int64_t` value.
+
+[`operator<<`](../api/basic_json_view/operator_ltlt.md) writes a view to a stream the way `basic_json`'s does, using
+the stream's `width`/`fill` for indentation.
