Expand description
The Read
trait allows for reading bytes from a source.
Required Methods§
Provided Methods§
sourcefn read_to_end(&mut self, buf: &mut Vec<u8>) -> Result<usize>
fn read_to_end(&mut self, buf: &mut Vec<u8>) -> Result<usize>
Available on crate feature
alloc
only.Read all bytes until EOF in this source, placing them into buf
.
sourcefn read_to_string(&mut self, buf: &mut String) -> Result<usize>
fn read_to_string(&mut self, buf: &mut String) -> Result<usize>
Available on crate feature
alloc
only.Read all bytes until EOF in this source, appending them to buf
.
sourcefn read_exact(&mut self, buf: &mut [u8]) -> Result
fn read_exact(&mut self, buf: &mut [u8]) -> Result
Read the exact number of bytes required to fill buf
.
