Struct rustc_middle::mir::mono::CodegenUnit
source · pub struct CodegenUnit<'tcx> {
name: Symbol,
items: FxHashMap<MonoItem<'tcx>, MonoItemData>,
size_estimate: usize,
primary: bool,
is_code_coverage_dead_code_cgu: bool,
}
Fields§
§name: Symbol
A name for this CGU. Incremental compilation requires that name be unique amongst all crates. Therefore, it should contain something unique to this crate (e.g., a module path) as well as the crate name and disambiguator.
items: FxHashMap<MonoItem<'tcx>, MonoItemData>
§size_estimate: usize
§primary: bool
§is_code_coverage_dead_code_cgu: bool
True if this is CGU is used to hold code coverage information for dead code, false otherwise.
Implementations§

pub fn make_primary(&mut self)
sourcepub fn items(&self) -> &FxHashMap<MonoItem<'tcx>, MonoItemData>
pub fn items(&self) -> &FxHashMap<MonoItem<'tcx>, MonoItemData>
The order of these items is non-determinstic.
sourcepub fn items_mut(&mut self) -> &mut FxHashMap<MonoItem<'tcx>, MonoItemData>
pub fn items_mut(&mut self) -> &mut FxHashMap<MonoItem<'tcx>, MonoItemData>
The order of these items is non-determinstic.
pub fn is_code_coverage_dead_code_cgu(&self) -> bool
sourcepub fn make_code_coverage_dead_code_cgu(&mut self)
pub fn make_code_coverage_dead_code_cgu(&mut self)
Marks this CGU as the one used to contain code coverage information for dead code.
pub fn mangle_name(human_readable_name: &str) -> String

something which is needed when forcing DepNode
s during red-green
evaluation. The query system will only call this method if
fingerprint_style()
is not FingerprintStyle::Opaque
.
It is always valid to return None
here, in which case incremental
compilation will treat the query as having changed instead of forcing it.source§impl<P> IntoQueryParam<P> for P

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.
