Trait Sample 

pub trait Sample:
    Copy
    + Send
    + Sync
    + 'static
    + Sealed {
    const ZERO: Self;
    const IS_F64: bool;

    // Required methods
    fn from_f32(value: f32) -> Self;
    fn to_f32(self) -> f32;
}

Audio sample scalar — f32 or f64.

Implemented by f32 and f64 only. The bound exists so the crate::Plugin trait can be parameterised over precision without leaking the full numeric trait surface.

Required Associated Constants

const ZERO: Self

Zero value of this precision.

const IS_F64: bool

Whether this sample type is f64. Lets format wrappers pick the processSetup::symbolicSampleSize field (VST3) or equivalent without runtime branching past the constant-fold.

Required Methods

fn from_f32(value: f32) -> Self

Widen a f32 to this precision (f32 → f32 is identity).

fn to_f32(self) -> f32

Narrow to f32 for handing back to the host.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
