Struct wasmer_wasix::runtime::resolver::InMemorySource

pub struct InMemorySource { /* private fields */ }

A Source that tracks packages in memory.

Primarily used during testing.

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.

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

pub fn packages(&self) -> &BTreeMap<String, Vec<PackageSummary>>

pub fn get( &self, package_name: &str, version: &Version ) -> Option<&PackageSummary>

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<InMemorySource> for InMemorySource

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

This method tests for self and other values to be equal, and is used by ==.

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

This method 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 PackageSpecifier ) -> 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 PackageSpecifier ) -> 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.
