Trait Read 

pub trait Read {
    // Required method
    fn read(&mut self, buf: &mut [u8]) -> Result<usize>;

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

no_std-compatible read/write traits used by streaming APIs. no_std-compatible read trait used by streaming interfaces.

This trait is intentionally close to std::io::Read so the same code can be shared across std and no_std builds.

Required Methods

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

Reads bytes into buf, returning the number of bytes read.

Provided Methods

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

Reads exactly buf.len() bytes into buf.

Returns:

• Ok(()) if the buffer was fully filled.
• Err(Error::Eof) if input ended early.
