Struct cargo::core::compiler::fingerprint::DepFingerprint

struct DepFingerprint {
    pkg_id: u64,
    name: InternedString,
    public: bool,
    only_requires_rmeta: bool,
    fingerprint: Arc<Fingerprint>,
}

Dependency edge information for fingerprints. This is generated for each dependency and is stored in a Fingerprint.

Fields

pkg_id: u64

The hash of the package id that this dependency points to

name: InternedString

The crate name we’re using for this dependency, which if we change we’ll need to recompile!

public: bool

Whether or not this dependency is flagged as a public dependency or not.

only_requires_rmeta: bool

Whether or not this dependency is an rmeta dependency or a “full” dependency. In the case of an rmeta dependency our dependency edge only actually requires the rmeta from what we depend on, so when checking mtime information all files other than the rmeta can be ignored.

fingerprint: Arc<Fingerprint>

The dependency’s fingerprint we recursively point to, containing all the other hash information we’d otherwise need.

Implementations

fn new( cx: &mut Context<'_, '_>, parent: &Unit, dep: &UnitDep ) -> CargoResult<DepFingerprint>

Trait Implementations

impl Clone for DepFingerprint

fn clone(&self) -> DepFingerprint

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'de> Deserialize<'de> for DepFingerprint

fn deserialize<D>(d: D) -> Result<DepFingerprint, D::Error>where D: Deserializer<'de>,

Serialize this value into the given Serde serializer.

Layout

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.
