Trait BlockingWrite 

pub trait BlockingWrite {
    type Error: Error;

    // Required method
    fn write_all(&mut self, buf: &[u8]) -> Result<(), Self::Error>;
}

BlockingWrite is the library’s abstraction for blocking write I/O.

It is similar to std::io::Write, and there is a blanket implementation of BlockingWrite for any implementation of Write. The reason for introducing BlockingWrite is that it allows json-streaming to be used in a no-std environment.

Note that json-streaming writes data to a BlockingWrite in many small chunks without any I/O buffering. It is the client’s responsibility to use std::io::BufWriter or similar for improved performance where desired.

Required Associated Types

type Error: Error

Required Methods

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

Dyn Compatibility

This trait is dyn compatible.

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

Implementors

impl<W: Write> BlockingWrite for W

Available on crate feature std only.

Blanket implementation that allows any std::io::Write implementation to be used seamlessly as BlockingWrite.
