Pool

Struct Pool 

Source
pub struct Pool<VS: VersionSet, N: PackageName = String> { /* private fields */ }
Expand description

A pool stores and internalizes data related to the available packages.

A pool never releases its memory until it is dropped. References returned by the pool will remain valid for the lifetime of the pool. This allows inserting into the pool without requiring a mutable reference to the pool. This is what we refer to as Frozen data can be added but old data can never be removed or mutated.

Implementations§

Source§

impl<VS: VersionSet, N: PackageName> Pool<VS, N>

Source

pub fn new() -> Self

Creates a new Pool

Source

pub fn intern_string(&self, name: impl Into<String> + AsRef<str>) -> StringId

Interns a generic string into the Pool and returns its StringId. Strings are deduplicated.

Source

pub fn resolve_string(&self, string_id: StringId) -> &str

Returns the string associated with the provided StringId.

Panics if the string is not found in the pool.

Source

pub fn intern_package_name<NValue>(&self, name: NValue) -> NameId
where NValue: Into<N>, N: Clone,

Interns a package name into the Pool, returning its NameId. Names are deduplicated. If the same name is inserted twice the same NameId will be returned.

The original name can be resolved using the Self::resolve_package_name function.

Source

pub fn resolve_package_name(&self, name_id: NameId) -> &N

Returns the package name associated with the provided NameId.

Panics if the package name is not found in the pool.

Source

pub fn lookup_package_name(&self, name: &N) -> Option<NameId>

Returns the NameId associated with the specified name or None if the name has not previously been interned using Self::intern_package_name.

Source

pub fn intern_solvable(&self, name_id: NameId, record: VS::V) -> SolvableId

Adds a solvable to a repo and returns it’s SolvableId.

Unlike some of the other interning functions this function does not deduplicate any of the inserted elements. A unique Id will be returned everytime this function is called.

Source

pub fn resolve_solvable(&self, id: SolvableId) -> &Solvable<VS::V>

Returns the solvable associated to the provided id

Panics if the solvable is not found in the pool

Source

pub fn intern_version_set( &self, package_name: NameId, version_set: VS, ) -> VersionSetId

Interns a version set into the Pool, returning its VersionSetId. The returned VersionSetId can be used to retrieve a reference to the original version set using [Self::resolve_version-set].

A version set is always associated with a specific package name to which it applies. The passed in package name can be retrieved using Self::resolve_version_set_package_name.

Version sets are deduplicated. This means that if the same version set is inserted twice they will share the same VersionSetId.

Source

pub fn resolve_version_set(&self, id: VersionSetId) -> &VS

Returns the version set associated with the provided id

Panics if the version set is not found in the pool

Source

pub fn resolve_version_set_package_name(&self, id: VersionSetId) -> NameId

Returns the package name associated with the provide id.

Panics if the version set is not found in the pool

Source

pub fn intern_version_set_union( &self, first: VersionSetId, others: impl Iterator<Item = VersionSetId>, ) -> VersionSetUnionId

Interns a union of two or more version sets and returns its VersionSetUnionId.

Version set unions are not deduplicated, and a unique id is returned on every invocation.

Source

pub fn resolve_version_set_union( &self, id: VersionSetUnionId, ) -> impl Iterator<Item = VersionSetId> + '_

Returns the version sets in the version set union with the given id.

Panics if there is no union with the given id.

Source

pub fn resolve_condition(&self, id: ConditionId) -> &Condition

Resolve the condition associated with the provided id.

Source

pub fn intern_condition(&self, condition: Condition) -> ConditionId

Interns a condition into the pool and returns its ConditionId. Conditions are deduplicated, so if the same condition is inserted twice the same ConditionId will be returned.
