# Struct std::process::ChildStderr 1.0.0 [−] [src]

    pub struct ChildStderr { /* fields omitted */ }

A handle to a child process's stderr.

This struct is used in the `stderr` field on `Child`.

## Trait Implementations

### `impl Read for ChildStderr`
[src]

#### `fn read(&mut self, buf: &mut [u8]) -> Result<usize>`
[src]

Pull some bytes from this source into the specified buffer, returning how many bytes were read. Read more

#### `unsafe fn initializer(&self) -> Initializer`
[src]

🔬 This is a nightly-only experimental API. (`read_initializer` #42788)

Determines if this `Read`er can work with buffers of uninitialized memory. Read more

#### `fn read_to_end(&mut self, buf: &mut Vec<u8>) -> Result<usize>`
[src]

Read all bytes until EOF in this source, placing them into `buf`. Read more

#### `fn read_to_string(&mut self, buf: &mut String) -> Result<usize>`
[src]

Read all bytes until EOF in this source, placing them into `buf`. Read more

#### `fn read_exact(&mut self, buf: &mut [u8]) -> Result<()>`
1.6.0
[src]

Read the exact number of bytes required to fill `buf`. Read more

#### `fn by_ref(&mut self) -> &mut Self where
Self: Sized,`
[src]

Creates a "by reference" adaptor for this instance of `Read`. Read more

#### `fn bytes(self) -> Bytes<Self> where
Self: Sized,`
[src]

Transforms this `Read` instance to an [`Iterator`] over its bytes. Read more

#### `fn chars(self) -> Chars<Self> where
Self: Sized,`
[src]

🔬 This is a nightly-only experimental API. (`io` #27802)

the semantics of a partial read/write of where errors happen is currently unclear and may change

Transforms this `Read` instance to an [`Iterator`] over [`char`]s. Read more

#### `fn chain<R: Read>(self, next: R) -> Chain<Self, R> where
Self: Sized,`
[src]

Creates an adaptor which will chain this stream with another. Read more

#### `fn take(self, limit: u64) -> Take<Self> where
Self: Sized,`
[src]

Creates an adaptor which will read at most `limit` bytes from it. Read more

### `impl Debug for ChildStderr`
1.16.0
[src]

#### `fn fmt(&self, f: &mut Formatter) -> Result`
[src]

Formats the value using the given formatter.

### `impl AsRawFd for ChildStderr`
1.2.0
[src]

#### `fn as_raw_fd(&self) -> RawFd`
[src]

This is supported on Unix only.

Extracts the raw file descriptor. Read more

### `impl IntoRawFd for ChildStderr`
1.4.0
[src]

#### `fn into_raw_fd(self) -> RawFd`
[src]

This is supported on Unix only.

Consumes this object, returning the raw underlying file descriptor. Read more

### `impl AsRawHandle for ChildStderr`
1.2.0
[src]

#### `fn as_raw_handle(&self) -> RawHandle`
[src]

This is supported on Windows only.

Extracts the raw handle, without taking any ownership.

### `impl IntoRawHandle for ChildStderr`
1.4.0
[src]

#### `fn into_raw_handle(self) -> RawHandle`
[src]

This is supported on Windows only.

Consumes this object, returning the raw underlying handle. Read more

## Search Tricks

Prefix searches with a type followed by a colon (e.g. `fn:`) to restrict the search to a given type.

Accepted types are: `fn`, `mod`, `struct`, `enum`, `trait`, `type`, `macro`, and `const`.

Search functions by type signature (e.g. `vec -> usize` or `* -> vec`)
