Trait Write 

pub trait Write {
    type Error: Error;

    // Required methods
    async fn write(&mut self, buf: &[u8]) -> Result<usize, Error<Self::Error>>;
    async fn flush(&mut self) -> Result<(), Error<Self::Error>>;

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

Available on crate feature async only.

Asynchronously write bytes to a destination.

Required Associated Types

type Error: Error

Error returned by the destination.

Required Methods

async fn write(&mut self, buf: &[u8]) -> Result<usize, Error<Self::Error>>

Write some bytes.

async fn flush(&mut self) -> Result<(), Error<Self::Error>>

Flush buffered output.

Provided Methods

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

Write all bytes, retrying interrupted operations.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
