Trait Read 

pub trait Read {
    // Required method
    fn read(&mut self, buf: &mut Vec<u8>) -> Result<bool, ReadError>;
}

Custom read abstraction that allows Reader to work without std::io::Read.

This trait is automatically implemented for &[u8] and, when the std feature is enabled, for any std::io::Read type.

Required Methods

fn read(&mut self, buf: &mut Vec<u8>) -> Result<bool, ReadError>

Read data into buf, appending to its contents.

Returns Ok(true) when at least one byte was appended to buf, or Ok(false) to signal end-of-input.

Implementations must not return Ok(true) without appending at least one byte. Doing so is a contract violation; rather than spinning or panicking, the Reader reports ReadErrorKind::NoProgress and stops reading.

Dyn Compatibility

This trait is dyn compatible.

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