#[non_exhaustive]
pub enum Feature {
    Snappy,
    Brotli,
    Gzip,
    Lz4,
    Zstd,
}

Expand description

List of features whose non-activation may cause a runtime error. Used to indicate which lack of feature caused Error::FeatureNotActive.

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.
