Struct ChannelLayoutTicket 

pub struct ChannelLayoutTicket { /* private fields */ }

The owned mirror of an AVChannelLayout.

The union is discriminated by order, and this type keeps that discrimination honest: mask is read and written only for the orders whose union arm is the bitmask, and map only for AV_CHANNEL_ORDER_CUSTOM, whose arm is a pointer. Reading the pointer arm as a mask would put a raw address in an owned mirror, which is the whole thing this type exists to stop.

Implementations

impl ChannelLayoutTicket

pub const fn order(&self) -> i32

The raw AVChannelOrder.

pub const fn channels(&self) -> i32

nb_channels, verbatim.

pub const fn mask(&self) -> u64

The channel bitmask, meaningful for every order but AV_CHANNEL_ORDER_CUSTOM, where it reads zero and Self::map carries the layout instead.

pub fn map(&self) -> &[CustomChannel]

The custom channel map — empty for every order but AV_CHANNEL_ORDER_CUSTOM.
