Struct rustc_middle :: ty :: typeck_results :: UserTypeAnnotationIndex Copy item path

impl UserTypeAnnotationIndex

pub const MAX_AS_U32: u32 = 4_294_967_040u32

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.

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 as_u32(self) -> u32

Extracts the value of this index as a u32.

pub const fn as_usize(self) -> usize

default fn fingerprint_style() -> FingerprintStyle

default fn to_fingerprint(&self, tcx: Tcx) -> Fingerprint

This method turns the parameters of a DepNodeConstructor into an opaque Fingerprint to be used in DepNode. Not all DepNodeParams support being turned into a Fingerprint (they don’t need to if the corresponding DepNode is anonymous).

It is always valid to return None here, in which case incremental compilation will treat the query as having changed instead of forcing it.
