Trait Read 

pub trait Read<'read>: Sized + Debug {
    type Error: Sized + Copy + Debug;

    // Required methods
    fn read_byte(&mut self) -> Result<u8, Self::Error>;
    fn read_exact(&mut self, slice: &mut [u8]) -> Result<(), Self::Error>;
}

A no-std io::Read alternative.

While plenty of crates define their own, we avoid external dependencies by once again defining our own. For those who wish to use embedded-io, please see core-json-embedded-io.

Required Associated Types

type Error: Sized + Copy + Debug

The type for errors when interacting with this reader.

Required Methods

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

Read a single byte from the reader.

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

Read into a slice from the reader.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
