Struct cargo::core::compiler::unit::UnitInterner

pub struct UnitInterner {
    state: RefCell<InternerState>,
}

A small structure used to “intern” Unit values.

A Unit is just a thin pointer to an internal UnitInner. This is done to ensure that Unit itself is quite small as well as enabling a very efficient hash/equality implementation for Unit. All units are manufactured through an interner which guarantees that each equivalent value is only produced once.

Fields

state: RefCell<InternerState>

Implementations

impl UnitInterner

pub fn new() -> UnitInterner

Creates a new blank interner

pub fn intern( &self, pkg: &Package, target: &Target, profile: Profile, kind: CompileKind, mode: CompileMode, features: Vec<InternedString>, is_std: bool, dep_hash: u64, artifact: IsArtifact, artifact_target_for_features: Option<CompileTarget> ) -> Unit

Creates a new unit from its components. The returned Unit’s fields will all be equivalent to the provided arguments, although they may not be the exact same instance.

fn intern_inner(&self, item: &UnitInner) -> Rc<UnitInner>

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.
