Struct InMemorySource

pub struct InMemorySource {
    named_packages: BTreeMap<String, Vec<NamedPackageSummary>>,
    hash_packages: HashMap<PackageHash, PackageSummary>,
}

A Source that tracks packages in memory.

Primarily used during testing.

Fields

named_packages: BTreeMap<String, Vec<NamedPackageSummary>>

hash_packages: HashMap<PackageHash, PackageSummary>

Implementations

impl InMemorySource

pub fn new() -> Self

pub fn from_directory_tree(dir: impl Into<PathBuf>) -> Result<Self, Error>

Recursively walk a directory, adding all valid WEBC files to the source.

pub fn add(&mut self, summary: PackageSummary)

Add a new PackageSummary to the InMemorySource.

Named packages are also made accessible by their hash.

pub fn add_webc(&mut self, path: impl AsRef<Path>) -> Result<(), Error>

pub fn get(&self, id: &PackageId) -> Option<&PackageSummary>

pub fn is_empty(&self) -> bool

pub fn len(&self) -> usize

Returns the number of packages in the source.

Trait Implementations

impl Clone for InMemorySource

fn clone(&self) -> InMemorySource

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for InMemorySource

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for InMemorySource

fn default() -> InMemorySource

Returns the “default value” for a type.

impl PartialEq for InMemorySource

fn eq(&self, other: &InMemorySource) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Source for InMemorySource

fn query<'life0, 'life1, 'async_trait>( &'life0 self, package: &'life1 PackageSource, ) -> Pin<Box<dyn Future<Output = Result<Vec<PackageSummary>, QueryError>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Ask this source which packages would satisfy a particular Dependency constraint.

fn latest<'life0, 'life1, 'async_trait>( &'life0 self, pkg: &'life1 PackageSource, ) -> Pin<Box<dyn Future<Output = Result<PackageSummary, QueryError>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Run Source::query() and get the PackageSummary for the latest version.
