Struct CompressionPolicy 

pub struct CompressionPolicy {
    pub encodings: Vec<String>,
    pub min_size: usize,
}

The rules that decide which encoding an answer carries.

The policy holds no server state, so the same rules can be used by any server that answers with a compressed body.

Fields

encodings: Vec<String>

The encodings that are offered, in the order they are preferred.

min_size: usize

The smallest body that is worth compressing.

Implementations

impl CompressionPolicy

pub fn pick(&self, accept_encoding: &str) -> Option<String>

The encoding the client asked for, when one of the offered encodings is accepted.

The offered encodings are tried in the order they are preferred, so the first one the client accepts is the one that is used.

Arguments

• &str - The accept-encoding header of the request.

Returns

• Option<String> - The encoding to answer with, when the client accepts one of the offered encodings.

pub fn accepted(&self, accept_encoding: &str) -> Vec<String>

The encodings the client accepts, without the ones it refused.

An encoding that is refused with a quality of zero is dropped, and the tokens are read in the case the client wrote them in.

Arguments

• &str - The accept-encoding header of the request.

Returns

• Vec<String> - The tokens the client accepts.

pub fn is_compressible(content_type: &str) -> bool

Whether a body of that content type is worth compressing.

A body that is already compressed is sent as it is, and the stream of events is never compressed. The rule does not depend on the encodings that are offered, so it is asked of the policy itself.

Arguments

• &str - The content type of the answer.

Returns

• bool - Whether the body may be compressed.

impl CompressionPolicy

pub fn get_encodings(&self) -> &Vec<String>

pub fn get_min_size(&self) -> usize

Trait Implementations

impl Default for CompressionPolicy

fn default() -> Self

Builds the policy that is used when none is given.
