Struct riffu::fourcc::FourCC

pub struct FourCC { /* fields omitted */ }

Implementations

impl FourCC

Represents the ASCII identifier of a chunk.

Example

use riffu::FourCC;
let good = FourCC::new(b"1234");
// let bad = FourCC::new(b"12345"); // won't compile

NOTE

1. AFAIK, the only valid identifier is in ASCII. I am not entirely sure what all the possible value ASCII can take. So we need to enforce correctness on that front too.
2. Are there other conversions that we are missing out on?

pub fn new(data: &[u8]) -> RiffResult<FourCC>

pub fn as_bytes(&self) -> &[u8; 4]

View &self struct as a &[u8].

pub fn into_bytes(self) -> [u8; 4]

Consume self and returns a [u8; 4].
