Struct rustc_middle::mir::mono::CodegenUnit

pub struct CodegenUnit<'tcx> {
    name: Symbol,
    items: FxIndexMap<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: FxIndexMap<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

impl<'tcx> CodegenUnit<'tcx>

pub fn new(name: Symbol) -> CodegenUnit<'tcx>

pub fn name(&self) -> Symbol

pub fn set_name(&mut self, name: Symbol)

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.
