pub struct ReadExact { /* private fields */ }

I/O-free coroutine for reading bytes into a buffer until it reaches a given amount of bytes.

Implementations

impl ReadExact

pub fn new(max: usize) -> Self

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

See Self::with_capacity for a custom buffer capacity.

pub fn with_capacity(capacity: usize, max: usize) -> Self

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

pub fn extend(&mut self, bytes: impl IntoIterator<Item = u8>)

Adds the given bytes the to inner buffer.

pub fn resume(&mut self, arg: Option<Io>) -> Result<Vec<u8>, Io>

Makes the read progress.
