Union mmtk::util::metadata::side_metadata::global::SideMetadataOffset
source · pub union SideMetadataOffset {
addr: Address,
rel_offset: usize,
}
Expand description
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§
source§impl SideMetadataOffset
impl SideMetadataOffset
sourcepub const fn addr(addr: Address) -> Self
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
).
sourcepub const fn rel(rel_offset: usize) -> Self
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
).
sourcepub const fn layout_after(spec: &SideMetadataSpec) -> SideMetadataOffset
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.
