Struct rupta::util::type_util::FieldByteOffsetCache

pub struct FieldByteOffsetCache<'tcx> { /* private fields */ }

Provides a way to effectively get the byte offsets of an ADT type’s fields

Implementations

impl<'tcx> FieldByteOffsetCache<'tcx>

pub fn new() -> FieldByteOffsetCache<'tcx>

pub fn get_field_byte_offset( &mut self, tcx: TyCtxt<'tcx>, base_ty: Ty<'tcx>, proj: &ProjectionElems ) -> usize

Get or compute the offset of the given proj of base_ty. If we cannot obtain the layout of base_ty, the offset would be 0

pub fn compute_fields_byte_offsets(&mut self, tcx: TyCtxt<'tcx>, ty: Ty<'tcx>)

Compute the byte offset for each field a struct type

Trait Implementations

impl<'tcx> Default for FieldByteOffsetCache<'tcx>

fn default() -> Self

Returns the “default value” for a type.
