Struct Take

pub struct Take<'a, R: Read + ?Sized> { /* private fields */ }

Reader adapter which limits the bytes read from an underlying reader.

Created by calling [Read::take].

Implementations

impl<'a, R: Read + ?Sized> Take<'a, R>

pub fn read_to_end(&mut self, buf: &mut Vec<u8>) -> Result<usize>

Available on crate feature alloc only.

Reads all bytes until EOF from the underlying reader into buf.

Trait Implementations

impl<'a, R: BufRead + ?Sized> BufRead for Take<'a, R>

fn fill_buf(&mut self) -> Result<&[u8]>

Returns data read from this reader, filling the internal buffer if needed.

fn consume(&mut self, amount: usize)

Marks the buffered data up to amount as consumed.

impl<'a, R: Read + ?Sized> Read for Take<'a, R>

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

Reads bytes from source into buf.

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

Reads bytes from source until buf is full.

fn take(&mut self, limit: u64) -> Take<'_, Self>

Creates an adapter which will read at most limit bytes.

fn read_to_limit(&mut self, buf: &mut Vec<u8>, limit: u64) -> Result<usize>

Available on crate feature alloc only.

Attempts to read up to limit bytes from the reader, allocating space in buf as needed.
