§`inner: &'static PackageIdInner`

## Implementations§

Source§

### impl PackageId

Source

#### pub fn try_new( name: impl Into<InternedString>, version: &str, sid: SourceId, ) -> CargoResult<PackageId>

Source

#### pub fn new( name: InternedString, version: Version, source_id: SourceId, ) -> PackageId

Source

#### pub fn name(self) -> InternedString

Source

#### pub fn version(self) -> &'static Version

Source

#### pub fn source_id(self) -> SourceId

Source

#### pub fn with_source_id(self, source: SourceId) -> PackageId

Source

#### pub fn map_source(self, to_replace: SourceId, replace_with: SourceId) -> Self

Source

#### pub fn stable_hash(self, workspace: &Path) -> PackageIdStableHash<'_>

Returns a value that implements a “stable” hashable value.

Stable hashing removes the path prefix of the workspace from path packages. This helps with reproducible builds, since this hash is part of the symbol metadata, and we don’t want the absolute path where the build is performed to affect the binary output.

Source

#### pub fn tarball_name(&self) -> String

Filename of the `.crate` tarball, e.g., `once_cell-1.18.0.crate`.

Source

#### pub fn to_spec(&self) -> PackageIdSpec

Convert a `PackageId` to a `PackageIdSpec`, which will have both the `PartialVersion` and `Url` fields filled in.
