Trait Sample 

pub unsafe trait Sample {
    const DEFAULT_FORMAT: Format;

    // Required methods
    fn test(format: Format) -> bool;
    fn describe() -> &'static str;
}

Available on crate feature alsa only.

Trait used to designate types which are sample-appropriate for Pcm.

Safety

This trait is unsafe to implement, because an incorrectly implemented format test might have safety implications.

Required Associated Constants

const DEFAULT_FORMAT: Format

The default format to use for this sample.

Required Methods

fn test(format: Format) -> bool

Test if the given format is appropriate for this sample type.

fn describe() -> &'static str

A static description of the sample type.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
