Struct mmtk::util::side_metadata::SideMetadataSpec

pub struct SideMetadataSpec {
    pub scope: SideMetadataScope,
    pub offset: usize,
    pub log_num_of_bits: usize,
    pub log_min_obj_size: usize,
}

This struct stores the specification of a side metadata bit-set. It is used as an input to the (inline) functions provided by the side metadata module.

Each plan or policy which uses a metadata bit-set, needs to create an instance of this struct.

For performance reasons, objects of this struct should be constants.

Fields

scope: SideMetadataScope

offset: usize

log_num_of_bits: usize

log_min_obj_size: usize
