Enum rustc_monomorphize::collector::CollectionMode

source ·

enum CollectionMode {
    UsedItems,
    MentionedItems,
}

Expand description

See module-level docs on some contect for “mentioned” items.

Variants§

§

UsedItems

Collect items that are used, i.e., actually needed for codegen.

Which items are used can depend on optimization levels, as MIR optimizations can remove uses.

§

MentionedItems

Collect items that are mentioned. The goal of this mode is that it is independent of optimizations: the set of “mentioned” items is computed before optimizations are run.

The exact contents of this set are not a stable guarantee. (For instance, it is currently computed after drop-elaboration. If we ever do some optimizations even in debug builds, we might decide to run them before computing mentioned items.) The key property of this set is that it is optimization-independent.
