Struct rustc_infer::infer::canonical::ir::EffectVid

pub struct EffectVid {
    private_use_as_methods_instead: u32,
}

An effect variable ID.

Handling effect infer variables happens separately from const infer variables because we do not want to reuse any of the const infer machinery. If we try to relate an effect variable with a normal one, we would ICE, which can catch bugs where we are not correctly using the effect var for an effect param. Fallback is also implemented on top of having separate effect and normal const variables.

Implementations

impl EffectVid

pub const MAX_AS_U32: u32 = 4_294_967_040u32

Maximum value the index can take, as a u32.

pub const MAX: EffectVid = _

Maximum value the index can take.

pub const ZERO: EffectVid = _

Zero value of the index.

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

Creates a new index from a given usize.

Panics

Will panic if value exceeds MAX.

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

Creates a new index from a given u32.

Panics

Will panic if value exceeds MAX.

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

Creates a new index from a given u16.

Panics

Will panic if value exceeds MAX.

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

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.

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.
