Enum Compressor 

Source 
#[non_exhaustive]
pub enum Compressor {
    Zstd {
        level: Option<i32>,
    },
    Zlib {
        level: Option<u32>,
    },
    Snappy,
}
Available on crate features zstd-compression or zlib-compression or snappy-compression only.
Expand description

The compressors that may be used to compress messages sent to and decompress messages returned from the server. Note that each variant requires enabling a corresponding feature flag.

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.
§

Zstd

Available on crate feature zstd-compression only.

zstd compression. See the zstd manual for more information.

Fields

§level: Option<i32>

The compression level to use. It is an error to specify a value outside of the supported compression levels returned by zstd::compression_level_range. If no value is specified, the default value (zstd::DEFAULT_COMPRESSION_LEVEL) will be used. Higher levels correlate to smaller compression but slower performance.

§

Zlib

Available on crate feature zlib-compression only.

zlib compression. See the zlib documentation for more information.

Fields

§level: Option<u32>

The compression level to use. If no value is specified, the default value (flate2::Compression::default) will be used. Higher levels correlate to smaller compression but slower performance.

§

Snappy

Available on crate feature snappy-compression only.

snappy compression. See the snappy documentation for more information.
