pub enum ContentEncoding {
    Identity,
    Brotli,
    Deflate,
    Gzip,
    Zstd,
}
Expand description

Represents a supported content encoding.

Includes a commonly-used subset of media types appropriate for use as HTTP content encodings. See IANA HTTP Content Coding Registry.

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.
§

Identity

Indicates the no-op identity encoding.

I.e., no compression or modification.

§

Brotli

A format using the Brotli algorithm.

§

Deflate

A format using the zlib structure with deflate algorithm.

§

Gzip

Gzip algorithm.

§

Zstd

Zstd algorithm.
