Struct PathHashMapping

Source 
pub struct PathHashMapping<T> { /* private fields */ }
Expand description

A PathHashMapping reads and writes line-oriented “{package_path}={hash}\n” files, e.g. “data/static_packages”. Deprecated.

Implementations§

Source§

impl<T> PathHashMapping<T>

Source

pub fn deserialize(reader: impl Read) -> Result<Self, PathHashMappingError>

Reads the line-oriented “package-path=hash” static_packages or cache_packages file. Validates the package paths and hashes.

Source

pub fn contents(&self) -> impl ExactSizeIterator<Item = &(PackagePath, Hash)>

Iterator over the contents of the mapping.

Source

pub fn into_contents(self) -> impl ExactSizeIterator<Item = (PackagePath, Hash)>

Iterator over the contents of the mapping, consuming self.

Source

pub fn hashes(&self) -> impl Iterator<Item = &Hash>

Iterator over the contained hashes.

Source

pub fn hash_for_package(&self, path: &PackagePath) -> Option<Hash>

Get the hash for a package.

Source

pub fn from_entries(entries: Vec<(PackagePath, Hash)>) -> Self

Create a PathHashMapping from a Vec of (PackagePath, Hash) pairs.

Source

pub fn serialize(&self, writer: impl Write) -> Result<(), PathHashMappingError>

Write a static_packages or cache_packages file.
