Struct CacheMiddlewareBuilder 

pub struct CacheMiddlewareBuilder<B, C, CM> { /* private fields */ }

Builder for constructing CacheMiddleware with a fluent API.

Obtained via CacheMiddleware::builder(). Both backend() and config() must be called before build().

See the crate-level documentation for usage examples.

Implementations

impl<B, C, CM> CacheMiddlewareBuilder<B, C, CM>

pub fn backend<NB>(self, backend: NB) -> CacheMiddlewareBuilder<Arc<NB>, C, CM>

where NB: CacheBackend,

Sets the cache backend.

pub fn config<NC>(self, configuration: NC) -> CacheMiddlewareBuilder<B, NC, CM>

Sets the cache configuration.

Use Config::builder() to create a configuration.

pub fn concurrency_manager<NCM>( self, concurrency_manager: NCM, ) -> CacheMiddlewareBuilder<B, C, NCM>

Sets the concurrency manager for dogpile prevention.

Defaults to NoopConcurrencyManager if not called.

pub fn cache_status_header(self, header_name: HeaderName) -> Self

Sets the header name for cache status.

The cache status header indicates whether a response was served from cache. Possible values are HIT, MISS, or STALE.

Defaults to x-cache-status if not set.

impl<B, C, CM> CacheMiddlewareBuilder<Arc<B>, C, CM>

where B: CacheBackend,

pub fn build(self) -> CacheMiddleware<B, C, CM>

Builds the cache middleware.

Both backend() and config() must be called before this method.

impl CacheMiddlewareBuilder<NotSet, NotSet, NoopConcurrencyManager>

pub fn new() -> Self

Creates a new builder. Equivalent to CacheMiddleware::builder().

Trait Implementations

impl Default for CacheMiddlewareBuilder<NotSet, NotSet, NoopConcurrencyManager>

fn default() -> Self

Returns the “default value” for a type.
