Struct std::io::TakeAdapter

struct TakeAdapter<R> { ... }
R: Readable<R>

Adapter for a stream that returns EOF after limit bytes are read.

See take extension method.

Fields

limit: u64
inner: &mut R

Methods

impl TakeAdapter<R> { ... }
R: Readable<R>

fn new(inner: &mut R, limit: u64) -> TakeAdapter<R>

source

Creates a new adapter for the given stream.
fn read(self: &mut TakeAdapter<R>, buf: &mut [u8]) -> Result<usize>

source

Reads from the stream into a provided buffer.
If successful, returns the number of bytes read. This may be less than the size of the provided buffer.

Mixins

impl TakeAdapter<R> { ... }
R: Readable<R>

mixin Readable<TakeAdapter<R>>

fn read_exact(self: &mut Self, buf: &mut [u8]) -> Result<()>

source

Fills the provided buffer by reading from the stream.
If stream had less bytes available than the size of the buffer, this method will return an Error::eof().
fn read_to_end(self: &mut Self, buf: &mut StringBuf) -> Result<usize>

source

Reads the entire stream into a StringBuf.
If successful, returns the number of bytes that were read.
