Struct IntParam 

pub struct IntParam {
    pub info: ParamInfo,
    /* private fields */
}

An integer parameter.

Fields

info: ParamInfo

Implementations

impl IntParam

pub fn new(info: ParamInfo) -> Self

Panics

Panics if info.default_plain is non-finite or doesn’t round-trip through i64. The cast f64 as i64 saturates silently - default_plain = -1.0 lands on -1 (fine), but default_plain = 1e30 saturates to i64::MAX and f64::NAN becomes 0. The derive populates default_plain from #[param(default = ...)]; a user-supplied float there is a programmer error, not a runtime condition we should silently absorb.

pub fn value(&self) -> i64

pub fn value_f32(&self) -> f32

Read the value widened to f32. Useful when an int param feeds a per-sample DSP loop that runs in f32.

pub fn value_f64(&self) -> f64

Read the value widened to f64.

pub fn value_usize(&self) -> usize

Read the value as a non-negative usize. Negatives clamp to 0; values above usize::MAX saturate.

pub fn value_i32(&self) -> i32

Read the value clamped to i32 range.

pub fn value_u8(&self) -> u8

Read the value clamped to u8 range (0..=255).

pub fn set_value(&self, v: i64)

Set the value, clamped to the declared range - symmetric with FloatParam::set_value. A corrupt preset or hostile automation value (i64::MAX into a [0, 8] param) must not reach the plugin, where it could index out of range and panic the audio thread. The bounds are normalized so a mis-ordered range can’t panic clamp.

pub fn id(&self) -> u32
