Trait Write

pub trait Write: Send + Sync {
    // Required methods
    fn write(&mut self, buf: &[u8]) -> IOResult<usize>;
    fn flush(&mut self) -> IOResult;

    // Provided method
    fn write_all(&mut self, buf: &[u8]) -> IOResult { ... }
}

Required Methods

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

fn flush(&mut self) -> IOResult

Provided Methods

fn write_all(&mut self, buf: &[u8]) -> IOResult

Write an entire buffer into this writer.

This function calls write() in a loop until exactly buf.len() bytes have been written, blocking if needed.

If you are using [WriteReady] to avoid blocking, you should not use this function. WriteReady::write_ready() returning true only guarantees the first call to write() will not block, so this function may still block in subsequent calls.

This function will panic if write() returns Ok(0).

Trait Implementations

impl Write for dyn Write

fn write_str(&mut self, s: &str) -> Result

Writes a string slice into this writer, returning whether the write succeeded.

fn write_char(&mut self, c: char) -> Result<(), Error>

Writes a char into this writer, returning whether the write succeeded.

fn write_fmt(&mut self, args: Arguments<'_>) -> Result<(), Error>

Glue for usage of the write! macro with implementors of this trait.
