Struct SplitPointIndex 

pub struct SplitPointIndex {
    private_use_as_methods_instead: u32 is 0..=4294967040,
}

A PointIndex with the lower bit encoding early/late inside a statement.

This is used to model overlap constraints within a MIR statement: if a source/destination are allowed to overlap then the source is read in SplitPointEffect::Early and the write is done in SplitPointEffect::Late.

Fields

private_use_as_methods_instead: u32 is 0..=4294967040

Implementations

impl SplitPointIndex

pub const MAX_AS_U32: u32 = 4294967040

Maximum value the index can take, as a u32.

pub const MAX: Self

Maximum value the index can take.

pub const ZERO: Self

Zero value of the index.

pub const fn from_usize(value: usize) -> Self

Creates a new index from a given usize.

Panics

Will panic if value exceeds MAX.

pub const fn from_u32(value: u32) -> Self

Creates a new index from a given u32.

Panics

Will panic if value exceeds MAX.

pub const fn from_u16(value: u16) -> Self

Creates a new index from a given u16.

Panics

Will panic if value exceeds MAX.

pub const unsafe fn from_u32_unchecked(value: u32) -> Self

Creates a new index from a given u32.

Safety

The provided value must be less than or equal to the maximum value for the newtype. Providing a value outside this range is undefined due to layout restrictions.

Prefer using from_u32.

pub const fn index(self) -> usize

Extracts the value of this index as a usize.

pub const fn as_u32(self) -> u32

Extracts the value of this index as a u32.

pub const fn as_usize(self) -> usize

Extracts the value of this index as a usize.

impl SplitPointIndex

pub fn new(point: PointIndex, effect: SplitPointEffect) -> SplitPointIndex

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.
