pub struct ReadStream { /* private fields */ }

I/O-free coroutine to read bytes into a buffer.

Implementations

impl ReadStream

pub const DEFAULT_CAPACITY: usize = 8_192usize

The default read buffer capacity.

pub fn new() -> Self

Creates a new coroutine to read bytes using a buffer with Self::DEFAULT_CAPACITY capacity.

See Self::with_capacity for a custom buffer capacity.

pub fn with_capacity(capacity: usize) -> Self

Creates a new coroutine to read bytes using a buffer with the given capacity.

pub fn capacity(&self) -> usize

Returns the buffer capacity.

pub fn truncate(&mut self, len: usize)

Shortens the buffer to the given length.

pub fn replace(&mut self, buffer: Vec<u8>)

Replaces the inner buffer with the given one.

pub fn resume(&mut self, arg: Option<StreamIo>) -> ReadStreamResult

Makes the read progress.

impl Default for ReadStream

fn default() -> Self
