Struct elba::retrieve::cache::Cache

pub struct Cache {
    pub layout: Layout,
    pub logger: Logger,
    // some fields omitted
}

The Cache encapsulates all of the global state required for elba to function.

This global state includes stuff like temporary places to download and build packages, places to store indices of packages, etc.

Note that a Cache can be located anywhere, including in the current directory!

Fields

layout: Layout

logger: Logger

Methods

impl Cache

pub fn from_disk(plog: &Logger, location: &Path) -> Res<Self>

pub fn checkout_source(     &self,     pkg: &PackageId,     loc: &DirectRes ) -> Result<Source, Error>

Retrieve the metadata of a package, loading it into the cache if necessary.

pub fn checkout_build(&self, hash: &BuildHash) -> Res<Option<Binary>>

If the build directory exists, returns it. Otherwise, give up and return None

pub fn checkout_tmp(&self, hash: &BuildHash) -> Res<OutputLayout>

Returns a lock on a temporary build directory. Note that the format of this directory should be an OutputLayout.

pub fn store_bins(&self, bins: &[(PathBuf, String)], force: bool) -> Res<()>

pub fn remove_bins(&self, query: &Spec, bins: &[&str]) -> Res<u32>

pub fn store_build(&self, from: &Path, hash: &BuildHash) -> Res<Binary>

pub fn get_indices(&self, index_reses: &[DirectRes]) -> Indices
