Implementations
sourceimpl SymbolIndex
impl SymbolIndex
sourceconst MAX_AS_U32: u32 = 4_294_967_040u32
const MAX_AS_U32: u32 = 4_294_967_040u32
Maximum value the index can take, as a u32
.
sourceconst fn from_usize(value: usize) -> Self
const fn from_usize(value: usize) -> Self
sourceconst unsafe fn from_u32_unchecked(value: u32) -> Self
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
.

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.
