Enum Channel 

#[non_exhaustive]
pub enum Channel {
    Left,
    Right,
    Center,
    LeftSurround,
    RightSurround,
    Lfe,
    Other,
}

One channel of a multi-channel programme.

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.

Left

Front left.

Right

Front right.

Center

Front center.

LeftSurround

Left surround.

RightSurround

Right surround.

Lfe

Low-frequency effects channel; excluded from loudness sum per BS.1770-4.

Other

Any other channel; treated as unweighted (1.0).

Implementations

impl Channel

pub const fn weight(self) -> f32

The channel’s contribution weight in the K-weighted sum, per BS.1770-4 §4.1. Returns 0.0 for Channel::Lfe.

Example

use ebur128_stream::Channel;
assert_eq!(Channel::Center.weight(), 1.0);
assert_eq!(Channel::LeftSurround.weight(), 1.41);
assert_eq!(Channel::Lfe.weight(), 0.0);  // excluded

Trait Implementations

impl Clone for Channel

fn clone(&self) -> Channel

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Channel

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Channel

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Hash for Channel

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 Channel

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

impl Serialize for Channel

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Copy for Channel

impl Eq for Channel

impl StructuralPartialEq for Channel
