# Struct rustc_middle::ty::EffectVid

source ·

    pub struct EffectVid {
        private_use_as_methods_instead: u32,
    }

Expand description

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§

source§

### impl EffectVid

source

#### pub const MAX_AS_U32: u32 = 4_294_967_040u32

Maximum value the index can take, as a `u32`.

source

#### pub const MAX: EffectVid = _

Maximum value the index can take.

source

#### pub const ZERO: EffectVid = _

Zero value of the index.

source

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

Creates a new index from a given `usize`.

##### §Panics

Will panic if `value` exceeds `MAX`.

source

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

Creates a new index from a given `u32`.

##### §Panics

Will panic if `value` exceeds `MAX`.

source

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

Creates a new index from a given `u16`.

##### §Panics

Will panic if `value` exceeds `MAX`.

source

#### 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`.

source

#### pub const fn index(self) -> usize

Extracts the value of this index as a `usize`.

source

#### pub const fn as_u32(self) -> u32

Extracts the value of this index as a `u32`.

source

#### pub const fn as_usize(self) -> usize

Extracts the value of this index as a `usize`.
