Struct mmtk::plan::plan_constraints::PlanConstraints[−][src]

pub struct PlanConstraints {
    pub moves_objects: bool,
    pub gc_header_bits: usize,
    pub gc_header_words: usize,
    pub num_specialized_scans: usize,
    pub max_non_los_copy_bytes: usize,
    pub needs_log_bit_in_header: bool,
    pub needs_log_bit_in_header_num: usize,
    pub barrier: BarrierSelector,
    pub needs_linear_scan: bool,
    pub needs_concurrent_workers: bool,
    pub generate_gc_trace: bool,
    pub needs_forward_after_liveness: bool,
}

This struct defines plan-specific constraints. Most of the constraints are constants. Each plan should declare a constant of this struct, and use the constant wherever possible. However, for plan-neutral implementations, these constraints are not constant.
