Holds information about a cached resource.

Fields

resource: String

The original resource name.

resource_path: PathBuf

Path to the cached resource.

meta_path: PathBuf

Path to the serialized meta.

etag: Option<String>

The ETAG of the resource from the time it was cached, if there was one.

expires: Option<f64>

Time that the freshness of this cached resource will expire.

creation_time: f64

Time this version of the resource was cached.

Methods

impl Meta

pub async fn from_cache<'_>(resource_path: &'_ Path) -> Result<Self, Error>

Get the Meta from a cached resource.

Examples

use cached_path::{cached_path, Meta};

let resource = "https://github.com/epwalsh/rust-cached-path/blob/master/README.md";
let path = cached_path(resource).await?;
let meta = Meta::from_cache(&path).await?;
assert_eq!(&meta.resource[..], resource);

pub fn is_fresh(&self) -> bool

Check if resource is still fresh.
