Struct rustc_hir_analysis::check::fn_ctxt::arg_matrix::ProvidedIdx

pub(crate) struct ProvidedIdx {
    private: u32,
}

Fields

private: u32

Implementations

impl ProvidedIdx

pub(crate) const MAX_AS_U32: u32 = 4_294_967_040u32

Maximum value the index can take, as a u32.

pub(crate) const MAX: Self = _

Maximum value the index can take.

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

Creates a new index from a given usize.

Panics

Will panic if value exceeds MAX.

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

Creates a new index from a given u32.

Panics

Will panic if value exceeds MAX.

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

Extracts the value of this index as a usize.

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

Extracts the value of this index as a u32.

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

Extracts the value of this index as a usize.

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.
