Enum mmtk::util::copy::CopySemantics

pub enum CopySemantics {
    DefaultCopy,
    Nursery,
    PromoteToMature,
    Mature,
}

CopySemantics describes the copying operation. It depends on the kinds of GC, and the space. For example, in a mature/major GC in a generational plan, the nursery should have PromoteToMature while the mature space should have Mature. This enum may be expanded in the future to describe more semantics.

Variants

DefaultCopy

The default copy behavior.

Nursery

Copy in nursery generation.

PromoteToMature

Promote an object from nursery to mature spaces.

Mature

Copy in mature generation.
