Trait FromBytes

Source

pub unsafe trait FromBytes: Copy + 'static {
    // Provided method
    fn from_bytes(bytes: &[u8]) -> Result<&Self>
       where Self: Sized { ... }
}

Expand description

Allows for reading plain data structures from a u8 slice

§Safety

This trait and its operations are only safe for structures which are purely composed of plain data and have a C-style memory layout aka. #[repr(C)]

Provided Methods§

Source

fn from_bytes(bytes: &[u8]) -> Result<&Self>
where Self: Sized,

Returns a reference to a single instance of Self represented by the specified bytes. Does not check for correct endianness.

§Errors

This function will return an error if:

The buffer is not big enough to read the requested structure (Error::InsufficientBuffer)
The buffers memory alignment is not ABI complaint with the requested structure (Error::Misaligned)
