Struct FourCharCode 

pub struct FourCharCode(pub [u8; 4]);

Four-character code (FourCC) for AU identifiers.

Used for manufacturer codes and subtype codes in AU registration. Must be exactly 4 ASCII characters.

Tuple Fields

0: [u8; 4]

Implementations

impl FourCharCode

pub const fn new(bytes: &[u8; 4]) -> Self

Create a new FourCharCode from a 4-byte array.

Panics

Debug builds will panic if any byte is not ASCII.

pub const fn as_u32(&self) -> u32

Get the FourCC as a 32-bit value (big-endian).

pub fn as_str(&self) -> &str

Get the FourCC as a string slice.

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

Get the raw bytes.

Trait Implementations

impl Clone for FourCharCode

fn clone(&self) -> FourCharCode

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for FourCharCode

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for FourCharCode

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for FourCharCode

fn eq(&self, other: &FourCharCode) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
