Struct AnimHeader 

pub struct AnimHeader {
    pub background_color: BackgroundColor,
    pub loop_count: u16,
}

Decoded §2.7.1.1 ANIM chunk — global animation parameters.

Constructed via AnimHeader::parse.

Fields

background_color: BackgroundColor

Background Color field, broken into BGRA components.

loop_count: u16

Loop Count field. 0 means “loop infinitely” per §2.7.1.1.

Implementations

impl AnimHeader

pub fn parse(payload: &[u8]) -> Result<Self, AnimError>

Parse the 6-byte ANIM chunk payload per RFC 9649 §2.7.1.1.

payload is the slice returned by crate::container::WebpChunk::payload for a chunk whose FourCC is crate::container::fourcc::ANIM.

pub const fn loops_forever(&self) -> bool

true when Loop Count == 0, which §2.7.1.1 defines as “infinite playback”.

Trait Implementations

impl Clone for AnimHeader

fn clone(&self) -> AnimHeader

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for AnimHeader

impl Debug for AnimHeader

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

Formats the value using the given formatter.

impl Eq for AnimHeader

impl PartialEq for AnimHeader

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