Struct PackageId

pub struct PackageId {
    inner: &'static PackageIdInner,
}

Identifier for a specific version of a package in a specific source.

Fields

inner: &'static PackageIdInner

Implementations

impl PackageId

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

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

pub fn name(self) -> InternedString

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

pub fn source_id(self) -> SourceId

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

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

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.

pub fn tarball_name(&self) -> String

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

pub fn to_spec(&self) -> PackageIdSpec

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

impl PackageId

pub fn as_activations_key( self, ) -> (InternedString, SourceId, SemverCompatibility)

Trait Implementations

impl Clone for PackageId

fn clone(&self) -> PackageId

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for PackageId

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for PackageId

fn deserialize<D>(d: D) -> Result<PackageId, D::Error>

where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for PackageId

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

Formats the value using the given formatter.

impl Hash for PackageId

fn hash<S: Hasher>(&self, state: &mut S)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for PackageId

fn cmp(&self, other: &PackageId) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for PackageId

fn eq(&self, other: &PackageId) -> 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 PartialOrd for PackageId

fn partial_cmp(&self, other: &PackageId) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl Serialize for PackageId

fn serialize<S>(&self, s: S) -> Result<S::Ok, S::Error>

where S: Serializer,

Serialize this value into the given Serde serializer.

impl Copy for PackageId

impl Eq for PackageId

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
