Trait cros_codecs::decoders::MappableHandle

pub trait MappableHandle {
    // Required methods
    fn read(&mut self, buffer: &mut [u8]) -> Result<()>;
    fn image_size(&mut self) -> usize;
}

A trait for types that can be mapped into the client’s address space.

Required Methods

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

The size of buffer must be equal to image_size(), or an error will be returned.
