Trait byte::TryRead [−] [src]

pub trait TryRead<'a, Ctx = ()> where
    Self: Sized, {
    fn try_read(bytes: &'a [u8], ctx: Ctx) -> Result<(Self, usize)>;
}

A data structure that can be deserialized. Types implement this trait can be read() from byte slice.

Required Methods

Try to read from bytes using context.

Read the value out of bytes; the bytes passed in is splitted by offset and should be read at head. If success, try_read() should return a tuple with the value and the number of bytes consumed.

Example

use byte::*;

// Demo type showing how to read boolean from bytes.
// This functionality is already provided by this crate.
pub struct Bool(bool);

impl<'a> TryRead<'a> for Bool {
    #[inline]
    fn try_read(bytes: &'a [u8], _ctx: ()) -> Result<(Self, usize)> {
        check_len(bytes, 1)?;

        Ok((Bool(bytes[0] != 0), 1))
    }
}
