Struct LocalFileId

struct LocalFileId {
    private_use_as_methods_instead: u32,
}

An index into a function’s list of global file IDs. That underlying list of local-to-global mappings will be embedded in the function’s record in the __llvm_covfun linker section.

Fields

private_use_as_methods_instead: u32

Implementations

impl LocalFileId

const MAX_AS_U32: u32 = 4_294_967_040u32

Maximum value the index can take, as a u32.

const MAX: Self

Maximum value the index can take.

const ZERO: Self

Zero value of the index.

const fn from_usize(value: usize) -> Self

Creates a new index from a given usize.

Panics

Will panic if value exceeds MAX.

const fn from_u32(value: u32) -> Self

Creates a new index from a given u32.

Panics

Will panic if value exceeds MAX.

const fn from_u16(value: u16) -> Self

Creates a new index from a given u16.

Panics

Will panic if value exceeds MAX.

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.

const fn index(self) -> usize

Extracts the value of this index as a usize.

const fn as_u32(self) -> u32

Extracts the value of this index as a u32.

const fn as_usize(self) -> usize

Extracts the value of this index as a usize.

Trait Implementations

impl Add<usize> for LocalFileId

type Output = LocalFileId

The resulting type after applying the + operator.

fn add(self, other: usize) -> Self

Performs the + operation.

impl Clone for LocalFileId

fn clone(&self) -> LocalFileId

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for LocalFileId

fn fmt(&self, fmt: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl From<LocalFileId> for u32

fn from(v: LocalFileId) -> u32

Converts to this type from the input type.

impl From<LocalFileId> for usize

fn from(v: LocalFileId) -> usize

Converts to this type from the input type.

impl From<u32> for LocalFileId

fn from(value: u32) -> Self

Converts to this type from the input type.

impl From<usize> for LocalFileId

fn from(value: usize) -> Self

Converts to this type from the input type.

impl Hash for LocalFileId

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

impl Idx for LocalFileId

fn new(value: usize) -> Self

fn index(self) -> usize

fn increment_by(&mut self, amount: usize)

fn plus(self, amount: usize) -> Self

impl PartialEq for LocalFileId

fn eq(&self, other: &LocalFileId) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Copy for LocalFileId

impl Eq for LocalFileId

impl StructuralPartialEq for LocalFileId

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.
