Struct FrameMeta 

#[non_exhaustive]
pub struct FrameMeta {
    pub layout: Layout,
    pub core_rate: u32,
    pub output_rate: u32,
    pub channels: [Option<Channel>; 8],
}

Copy metadata for one decoded frame or a finished stream.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

layout: Layout

core_rate: u32

AAC core rate (before SBR upsample). 0 if nothing was decoded.

output_rate: u32

Presentation rate (2× core for HE). Matches super::Frame::sample_rate.

channels: [Option<Channel>; 8]

Per-plane labels; unused slots are None.

Implementations

impl FrameMeta

pub const EMPTY: Self

pub fn from_labels( layout: Layout, core_rate: u32, output_rate: u32, labels: &[Channel], ) -> Self
