Struct Volume 

#[repr(transparent)]
pub struct Volume(pub i16);

A 16-bit signed SPU voice/main volume.

Static voice/main volume uses -0x4000..=0x3FFF as its linear range. Positive magnitudes are the normal “louder” direction and a negative one inverts the phase. A value outside the range is limited to it when it is written to the register, so it never reaches the sweep-mode bit.

Tuple Fields

0: i16

Implementations

impl Volume

pub const SILENCE: Self

Silence.

pub const MAX: Self

Maximum linear-positive volume (0x3FFF = +1.0).

pub const HALF: Self

Half-scale convenience (0x2000 ≈ 0.5).

pub const fn linear(num: u16, den: u16) -> Self

Build from a normalized float-ish 0.0..=1.0 value without actually using floats (since we’re no_std, no FPU). num and den are integer – Volume::linear(3, 4) is 0.75.

Trait Implementations

impl Clone for Volume

fn clone(&self) -> Volume

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Volume

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

Formats the value using the given formatter.

impl Default for Volume

fn default() -> Self

Returns the “default value” for a type.

impl PartialEq for Volume

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