Struct rustc_query_system::dep_graph::graph::DepNodeIndex

pub struct DepNodeIndex {
    private_use_as_methods_instead: u32,
}

Fields

private_use_as_methods_instead: u32

Implementations

impl DepNodeIndex

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.

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 const fn index(self) -> usize

Extracts the value of this index as a usize.

pub const fn as_u32(self) -> u32

Extracts the value of this index as a u32.

pub const fn as_usize(self) -> usize

Extracts the value of this index as a usize.

impl DepNodeIndex

const SINGLETON_DEPENDENCYLESS_ANON_NODE: DepNodeIndex = DepNodeIndex::ZERO

pub const FOREVER_RED_NODE: DepNodeIndex = _

🔬This is a nightly-only experimental API. (extend_one)

Extends a collection with exactly one element.

fn extend_reserve(&mut self, additional: usize)

🔬This is a nightly-only experimental API. (extend_one)

Reserves capacity in a collection for the given number of additional elements.

impl From<DepNodeIndex> for QueryInvocationId

fn from(dep_node_index: DepNodeIndex) -> Self

Converts to this type from the input type.

impl From<DepNodeIndex> for u32

fn from(v: DepNodeIndex) -> u32

Converts to this type from the input type.

fn from(v: DepNodeIndex) -> usize

Converts to this type from the input type.

impl From<u32> for DepNodeIndex

fn from(value: u32) -> Self

Converts to this type from the input type.

impl From<usize> for DepNodeIndex

fn from(value: usize) -> Self

Converts to this type from the input type.

impl FromIterator<DepNodeIndex> for EdgesVec

fn from_iter<T>(iter: T) -> Self

where T: IntoIterator<Item = DepNodeIndex>,

Creates a value from an iterator.

impl Hash for DepNodeIndex

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 PartialEq for DepNodeIndex

fn eq(&self, other: &DepNodeIndex) -> 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 StructuralPartialEq for DepNodeIndex

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.
