Uuid

uuid — UUID box

UuidInfo

uinf — UUID info super-box

Unknown(u32)

Unknown box type (raw 4-byte code stored for pass-through).

Implementations

impl BoxType

pub fn from_u32(code: u32) -> Self

Decode a BoxType from its 4-byte big-endian representation.

pub fn to_u32(&self) -> u32

Encode this BoxType as its 4-byte big-endian representation.

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

Return the 4 ASCII bytes for this box type.

pub fn is_superbox(&self) -> bool

Return true if this box type is a super-box that may contain children.

Trait Implementations

impl Clone for BoxType

fn clone(&self) -> BoxType

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for BoxType

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

Formats the value using the given formatter.

impl PartialEq for BoxType

fn eq(&self, other: &BoxType) -> 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.
