Struct rustc_middle::mir::interpret::allocation::init_mask::InitMaskMaterialized

struct InitMaskMaterialized {
    blocks: Vec<u64>,
}

The actual materialized blocks of the bitmask, when we can’t keep the InitMask lazy.

Fields

blocks: Vec<u64>

Implementations

impl InitMaskMaterialized

const BLOCK_SIZE: u64 = 64u64

fn new(size: Size, state: bool) -> Self

fn bit_index(bits: Size) -> (usize, usize)

fn size_from_bit_index(block: impl TryInto<u64>, bit: impl TryInto<u64>) -> Size

fn is_range_initialized(&self, start: Size, end: Size) -> Result<(), AllocRange>

Checks whether the range is entirely initialized.

Returns Ok(()) if it’s initialized. Otherwise returns a range of byte indexes for the first contiguous span of the uninitialized access.

fn set_range_inbounds(&mut self, start: Size, end: Size, new_state: bool)

fn get(&self, i: Size) -> bool

fn grow(&mut self, len: Size, amount: Size, new_state: bool)

fn find_bit(&self, start: Size, end: Size, is_init: bool) -> Option<Size>

Returns the index of the first bit in start..end (end-exclusive) that is equal to is_init.

Trait Implementations

impl Clone for InitMaskMaterialized

fn clone(&self) -> InitMaskMaterialized

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for InitMaskMaterialized

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<D: TyDecoder> Decodable<D> for InitMaskMaterialized

fn decode(decoder: &mut D) -> Self

impl<E: TyEncoder> Encodable<E> for InitMaskMaterialized

fn encode(&self, encoder: &mut E)

impl Hash for InitMaskMaterialized

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<'__ctx> HashStable<StableHashingContext<'__ctx>> for InitMaskMaterialized

fn hash_stable( &self, __hcx: &mut StableHashingContext<'__ctx>, __hasher: &mut StableHasher, )

impl PartialEq for InitMaskMaterialized

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

Tests for self and other values to be equal, and is used by ==.

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

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.
