Struct rustc_middle::mir::mono::CodegenUnit

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

impl<'tcx> CodegenUnit<'tcx>

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

pub fn name(&self) -> Symbol

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

pub fn is_primary(&self) -> bool

pub fn make_primary(&mut self)

pub fn items(&self) -> &FxHashMap<MonoItem<'tcx>, MonoItemData>

The order of these items is non-determinstic.

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

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

pub fn compute_size_estimate(&mut self)

pub fn size_estimate(&self) -> usize

Should only be called if compute_size_estimate has previously been called.

pub fn contains_item(&self, item: &MonoItem<'tcx>) -> bool

pub fn work_product_id(&self) -> WorkProductId

pub fn previous_work_product(&self, tcx: TyCtxt<'_>) -> WorkProduct

pub fn items_in_deterministic_order( &self, tcx: TyCtxt<'tcx> ) -> Vec<(MonoItem<'tcx>, MonoItemData)>

pub fn codegen_dep_node(&self, tcx: TyCtxt<'tcx>) -> DepNode

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.
