Take in futures_lite::io - Rust (original) (raw)

pub struct Take<R> { /* private fields */ }

Expand description

Source§

Source

Returns the number of bytes before this adapter will return EOF.

Note that EOF may be reached sooner if the underlying reader is shorter than the limit.

§Examples

use futures_lite::io::{AsyncReadExt, Cursor};

let reader = Cursor::new("hello");

let reader = reader.take(3);
assert_eq!(reader.limit(), 3);

Source

Puts a limit on the number of bytes.

Changing the limit is equivalent to creating a new adapter with AsyncReadExt::take().

§Examples

use futures_lite::io::{AsyncReadExt, Cursor};

let reader = Cursor::new("hello");

let mut reader = reader.take(10);
assert_eq!(reader.limit(), 10);

reader.set_limit(3);
assert_eq!(reader.limit(), 3);

Source

Gets a reference to the underlying reader.

§Examples

use futures_lite::io::{AsyncReadExt, Cursor};

let reader = Cursor::new("hello");

let reader = reader.take(3);
let r = reader.get_ref();

Source

Gets a mutable reference to the underlying reader.

§Examples

use futures_lite::io::{AsyncReadExt, Cursor};

let reader = Cursor::new("hello");

let mut reader = reader.take(3);
let r = reader.get_mut();

Source

Unwraps the adapter, returning the underlying reader.

§Examples

use futures_lite::io::{AsyncReadExt, Cursor};

let reader = Cursor::new("hello");

let reader = reader.take(3);
let reader = reader.into_inner();
