Enum kvarn::comprash::UriKey

source ·
pub enum UriKey {
    Path(CompactString),
    PathQuery(PathQuery),
}
Expand description

A key for an Uri used in ResponseCache.

This is, for now, an opaque type in it’s API. Though, you can extract the path and query through matching.

Variants§

§

Path(CompactString)

Uri with only a path component.

Searching the cache with this should be avoided. See Self::call_all.

§

PathQuery(PathQuery)

Uri with a path and optional query.

See PathQuery.

Implementations§

source§

impl UriKey

source

pub fn path_and_query(uri: &Uri) -> Self

Constructs a new UriKey from uri.

This variant will math both Self::PathQuery and Self::Path if Self::call_all is called on it.

source

pub fn call_all<T>( self, callback: impl FnMut(&Self) -> Option<T> ) -> (Self, Option<T>)

Tries to get type T from callback using current variant and other variants with fewer data. Returns Self which got a result from callback or, if none, truncated to Self::Path.

§Examples
use kvarn::prelude::*;
let key = UriKey::path_and_query(&Uri::from_static("https://icelk.dev/status?format=json"));

// First gets called once with key as UriKey::PathQuery("/status?format=json")
// then, the query gets truncated and we get a key as UriKey::Path("/status").
let (_key, found) = key.call_all(|key| {
    match key {
        UriKey::Path(path) if *path == "/status" => Some(true),
        _ => None
    }
});

assert_eq!(found, Some(true));
