#[non_exhaustive]
pub enum SampleFormat { I8, I16, I32, I64, U8, U16, U32, U64, F32, F64, }
Expand description

Format that each sample has.

Variants (Non-exhaustive)§

This enum is marked as 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.
