Trait Implementations

impl Clone for CrateNum

fn clone(&self) -> CrateNum

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for CrateNum

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

Formats the value using the given formatter.

impl<D: Decoder> Decodable<D> for CrateNum

default fn decode(d: &mut D) -> Result<CrateNum, D::Error>

impl Display for CrateNum

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

Formats the value using the given formatter.

impl<E: Encoder> Encodable<E> 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.

default fn encode(&self, s: &mut E) -> Result<(), E::Error>

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, 

Feeds a slice of this type into the given Hasher.

impl<CTX: HashStableContext> HashStable<CTX> for CrateNum

fn hash_stable(&self, hcx: &mut CTX, hasher: &mut StableHasher)

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

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.

#[must_use]

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

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

#[must_use]

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

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

#[must_use]

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

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

#[must_use]

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

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