Implementations

impl Mutability

pub fn invert(self) -> Self

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 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 copy 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

Formats the value using the given formatter.

impl<__D: Decoder> Decodable<__D> for Mutability

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

impl<__E: Encoder> Encodable<__E> for Mutability

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

impl Hash for Mutability

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,

Feeds a slice of this type into the given Hasher.

impl<__CTX> HashStable<__CTX> for Mutabilitywhere
    __CTX: HashStableContext,

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

impl Ord for Mutability

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

This method returns an Ordering between self and other.

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

Compares and returns the maximum of two values.

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

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Selfwhere
    Self: Sized + PartialOrd<Self>,

Restrict a value to a certain interval.

impl PartialEq<Mutability> for Mutability

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

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

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

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

impl PartialOrd<Mutability> 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

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

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

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

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

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

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

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

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.
