Fields§

§metadata_loader: Box<MetadataLoaderDyn>§metas: IndexVec<CrateNum, Option<Box<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.

§alloc_error_handler_kind: Option<AllocatorKind>

This crate needs an allocation error handler 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.

§has_alloc_error_handler: bool

This crate has a #[alloc_error_handler] item.

§unused_externs: Vec<Symbol>

Unused externs of the crate
