pub struct DefaultPredicate(/* private fields */);
Available on crate features compression-br or compression-deflate or compression-gzip or compression-zstd only.
Expand description

The default predicate used by Compression and CompressionLayer.

This will compress responses unless:

  • They’re gRPC, which has its own protocol specific compression scheme.
  • It’s an image as determined by the content-type starting with image/.
  • They’re Server-Sent Events (SSE) as determined by the content-type being text/event-stream.
  • The response is less than 32 bytes.

§Configuring the defaults

DefaultPredicate doesn’t support any configuration. Instead you can build your own predicate by combining types in this module:

use tower_http::compression::predicate::{SizeAbove, NotForContentType, Predicate};

// slightly large min size than the default 32
let predicate = SizeAbove::new(256)
    // still don't compress gRPC
    .and(NotForContentType::GRPC)
    // still don't compress images
    .and(NotForContentType::IMAGES)
    // also don't compress JSON
    .and(NotForContentType::const_new("application/json"));
