Implementations

impl Mutability

pub fn invert(self) -> Mutability

pub fn prefix_str(self) -> &'static str

Returns "" (empty string) or "mut " depending on the mutability.

pub fn ref_prefix_str(self) -> &'static str

Returns "&" or "&mut " depending on the mutability.

pub fn ptr_str(self) -> &'static str

Returns "const" or "mut" depending on the mutability.

pub fn mutably_str(self) -> &'static str

Returns "" (empty string) or "mutably " depending on the mutability.

pub fn is_mut(self) -> bool

Return true if self is mutable

pub fn is_not(self) -> bool

Return true if self is not mutable

Trait Implementations

impl Clone for Mutability

fn clone(&self) -> Mutability

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Mutability

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

Formats the value using the given formatter.

impl<__D> Decodable<__D> for Mutability

where __D: Decoder,

fn decode(__decoder: &mut __D) -> Mutability

impl<__E> Encodable<__E> for Mutability

where __E: Encoder,

fn encode(&self, __encoder: &mut __E)

impl Hash for Mutability

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

where __H: Hasher,

Feeds this value into the given Hasher.

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

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl<__CTX> HashStable<__CTX> for Mutability

fn hash_stable( &self, __hcx: &mut __CTX, __hasher: &mut StableHasher<SipHasher128>, )

impl Ord for Mutability

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

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for Mutability

fn eq(&self, other: &Mutability) -> 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 PartialOrd for Mutability

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

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

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

Tests less than (for self and other) and is used by the < operator.

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

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

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

Tests greater than (for self and other) and is used by the > operator.

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

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

impl<I: Interner> TypeFoldable<I> for Mutability

fn try_fold_with<F: FallibleTypeFolder<I>>( self, _: &mut F, ) -> Result<Self, F::Error>

The entry point for folding. To fold a value t with a folder f call: t.try_fold_with(f).

fn fold_with<F: TypeFolder<I>>(self, _: &mut F) -> Self

The entry point for folding. To fold a value t with a folder f call: t.fold_with(f).

impl<I: Interner> TypeVisitable<I> for Mutability

fn visit_with<F: TypeVisitor<I>>(&self, _: &mut F) -> F::Result

The entry point for visiting. To visit a value t with a visitor v call: t.visit_with(v).

impl Copy for Mutability

impl Eq for Mutability

impl StructuralPartialEq for Mutability

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.
