Implementations§

source§

impl Handle

source

const NULL_DISCRIMINANT: u32 = 0u32

source

const PSEUDO_DISCRIMINANT: u32 = 1u32

source

const THREAD_DISCRIMINANT: u32 = 2u32

source

fn discriminant(self) -> u32

source

fn data(self) -> u32

source

fn packed_disc_size() -> u32

source

fn to_packed(self) -> u32

Converts a handle into its machine representation.

The upper Self::packed_disc_size() bits are used to store a discriminant corresponding to the handle variant. The remaining bits are used for the variant’s field.

None of this layout is guaranteed to applications by Windows or Miri.

source

fn new(discriminant: u32, data: u32) -> Option<Self>

source

fn from_packed(handle: u32) -> Option<Self>

see docs for to_packed

source

pub fn to_scalar(self, cx: &impl HasDataLayout) -> Scalar

source

pub fn from_scalar<'tcx>( handle: Scalar, cx: &impl HasDataLayout, ) -> InterpResult<'tcx, Option<Self>>

impl PartialEq for Handle

source§

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

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

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.

Layout§

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
