Enum MapKey 

pub enum MapKey {
    Bool(bool),
    I32(i32),
    I64(i64),
    U32(u32),
    U64(u64),
    String(String),
}

Available on crate feature dynamic only.

A protobuf map key.

Variants are limited to those allowed by the proto spec: floats, bytes, and message/enum keys are forbidden.

Variants

Bool(bool)

bool.

I32(i32)

int32 / sint32 / sfixed32.

I64(i64)

int64 / sint64 / sfixed64.

U32(u32)

uint32 / fixed32.

U64(u64)

uint64 / fixed64.

String(String)

string.

Implementations

impl MapKey

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

The proto default for the given map-key kind.

Panics

Panics if kind is not a legal map-key shape (floats, bytes, messages, and enums are forbidden by the proto spec). The pool builder rejects such map declarations, so this only fires for hand-constructed misuse.

Trait Implementations

impl Clone for MapKey

fn clone(&self) -> MapKey

Returns a duplicate 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 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,

Restrict a value to a certain interval.

impl PartialEq for MapKey

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

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.
