Struct rustc_metadata::creader::CStore

pub struct CStore {
    metas: IndexVec<CrateNum, Option<Lrc<CrateMetadata>>>,
    injected_panic_runtime: Option<CrateNum>,
    allocator_kind: Option<AllocatorKind>,
    has_global_allocator: bool,

Fields

metas: IndexVec<CrateNum, Option<Lrc<CrateMetadata>>>

injected_panic_runtime: Option<CrateNum>

allocator_kind: Option<AllocatorKind>

This crate needs an allocator and either provides it itself, or finds it in a dependency. If the above is true, then this field denotes the kind of the found allocator.

has_global_allocator: bool

This crate has a #[global_allocator] item.
