impl Eq for CrateNum

impl Hash for CrateNum

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,

impl Idx for CrateNum

fn new(value: usize) -> Self

fn index(self) -> usize

fn increment_by(&mut self, amount: usize)

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

impl Ord for CrateNum

fn cmp(&self, other: &CrateNum) -> Ordering

This method returns an [Ordering] between self and other.

#[must_use] fn max(self, other: Self) -> Self

Compares and returns the maximum of two values.

#[must_use] fn min(self, other: Self) -> Self

Compares and returns the minimum of two values.

#[must_use] fn clamp(self, min: Self, max: Self) -> Self

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

Restrict a value to a certain interval.

impl PartialEq<CrateNum> for CrateNum

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

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=.

impl PartialOrd<CrateNum> for CrateNum

fn partial_cmp(&self, other: &CrateNum) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &CrateNum) -> bool

This method tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &CrateNum) -> bool

This method tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &CrateNum) -> bool

This method tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &CrateNum) -> bool

This method tests greater than or equal to (for self and other) and is used by the >= operator.

impl StructuralEq for CrateNum

impl StructuralPartialEq for CrateNum

impl UseSpecializedDecodable for CrateNum

fn default_decode<D: Decoder>(d: &mut D) -> Result<CrateNum, D::Error>

Defaults to returning an error (see SpecializationError).

impl UseSpecializedEncodable for CrateNum

As a local identifier, a CrateNum is only meaningful within its context, e.g. within a tcx. Therefore, make sure to include the context when encode a CrateNum.

fn default_encode<E: Encoder>(&self, e: &mut E) -> Result<(), E::Error>

Defaults to returning an error (see SpecializationError).
