Struct FrameRef 

pub struct FrameRef<'a> {
    pub data: Cow<'a, [u8]>,
    pub alpha_data: Option<Cow<'a, [u8]>>,
    pub duration_ms: u32,
}

A single frame from an animated AVIF, with zero-copy when possible.

The data field is Cow::Borrowed when the frame lives in a single contiguous mdat extent, and Cow::Owned when extents must be concatenated.

Fields

data: Cow<'a, [u8]>

alpha_data: Option<Cow<'a, [u8]>>

Alpha channel data for this frame, if the animation has a separate alpha track.

duration_ms: u32
