Enumerates the various representations of the ordering of audio channels. Must be kept synchronized with media::ChannelLayout from Chromium. See media\base\channel_layout.h

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Channels are not explicitly mapped to speakers.

CEF_CHANNEL_LAYOUT_STEREO_AND_KEYBOARD_MIC = 30

Deprecated, but keeping the enum value for UMA consistency. Front L, Front R, Front C. Front C contains the keyboard mic audio. This layout is only intended for input for WebRTC. The Front C channel is stripped away in the WebRTC audio input pipeline and never seen outside of that.

Trait Implementations

impl Clone for cef_channel_layout_t

fn clone(&self) -> cef_channel_layout_t

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for cef_channel_layout_t

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

Formats the value using the given formatter.

impl Hash for cef_channel_layout_t

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for cef_channel_layout_t

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