Union mmtk::util::metadata::side_metadata::SideMetadataOffset

pub union SideMetadataOffset {
    addr: Address,
    rel_offset: usize,
}

A union of Address or relative offset (usize) used to store offset for a side metadata spec. If a spec is contiguous side metadata, it uses address. Othrewise it uses usize.

Fields

addr: Address

rel_offset: usize

Implementations

impl SideMetadataOffset

pub const fn addr(addr: Address) -> Self

Get an offset for a fixed address. This is usually used to set offset for the first spec (subsequent ones can be laid out with layout_after).

pub const fn rel(rel_offset: usize) -> Self

Get an offset for a relative offset (usize). This is usually used to set offset for the first spec (subsequent ones can be laid out with layout_after).

pub const fn layout_after(spec: &SideMetadataSpec) -> SideMetadataOffset

Get an offset after a spec. This is used to layout another spec immediately after this one.

Trait Implementations

impl Clone for SideMetadataOffset

fn clone(&self) -> SideMetadataOffset

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Hash for SideMetadataOffset

fn hash<H: Hasher>(&self, state: &mut H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for SideMetadataOffset

fn eq(&self, other: &Self) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
