Trait BlockingRead 

pub trait BlockingRead {
    type Error: Error;

    // Required method
    fn read(&mut self) -> Result<Option<u8>, Self::Error>;
}

BlockingRead is the library’s abstraction for blocking read I/O.

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

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

Required Associated Types

type Error: Error

Required Methods

fn read(&mut self) -> Result<Option<u8>, Self::Error>

Dyn Compatibility

This trait is dyn compatible.

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

Implementors

impl<R: Read> BlockingRead for R

Available on crate feature std only.

Blanket implementation that allows any std::io::Read implementation to be used seamlessly as BlockingRead.
