Implementations

impl MapKey

pub fn default_value(kind: &Kind) -> Self

Returns the default value for the given protobuf type kind.

Panics

Panics if kind is not a valid map key type (an integral type or string).

pub fn is_default(&self, kind: &Kind) -> bool

Returns true if this is the default value for the given protobuf type kind.

Panics

Panics if kind is not a valid map key type (an integral type or string).

pub fn is_valid(&self, kind: &Kind) -> bool

Returns true if this map key can be encoded as the given Kind.

pub fn as_bool(&self) -> Option<bool>

Returns the value if it is a MapKey::Bool, or None if it is any other type.

Returns a mutable reference to the value if it is a MapKey::I64, or None if it is any other type.

pub fn as_i32(&self) -> Option<i32>

Returns the value if it is a MapKey::I32, or None if it is any other type.

pub fn as_i32_mut(&mut self) -> Option<&mut i32>

Returns a mutable reference to the value if it is a MapKey::I32, or None if it is any other type.

pub fn as_str(&self) -> Option<&str>

Returns the value if it is a MapKey::String, or None if it is any other type.

pub fn as_string_mut(&mut self) -> Option<&mut String>

Returns a mutable reference to the value if it is a MapKey::String, or None if it is any other type.

Trait Implementations

impl Clone for MapKey

fn clone(&self) -> MapKey

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for MapKey

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

Formats the value using the given formatter.

impl From<MapKey> for Value

fn from(value: MapKey) -> Self

Converts to this type from the input type.

impl Hash for MapKey

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 Ord for MapKey

fn cmp(&self, other: &MapKey) -> 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 + PartialOrd,

Restrict a value to a certain interval.

impl PartialEq for MapKey

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

fn partial_cmp(&self, other: &MapKey) -> 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.
