Struct protobuf::reflect::EnumValueDescriptor

pub struct EnumValueDescriptor { /* private fields */ }

Description for enum variant.

Used in reflection.

Implementations

impl EnumValueDescriptor

pub fn proto(&self) -> &EnumValueDescriptorProto

.proto object which declared this value.

pub fn name(&self) -> &str

Name of enum variant as specified in proto file

pub fn full_name(&self) -> String

Fully qualified enum value name: fully qualified enum name followed by value name.

pub fn value(&self) -> i32

i32 value of the enum variant

pub fn enum_descriptor(&self) -> &EnumDescriptor

Get descriptor of enum holding this value.

pub fn cast<E: EnumFull>(&self) -> Option<E>

Convert this value descriptor into proper enum object.

let value: EnumValueDescriptor = NullValue::NULL_VALUE.descriptor();
let null: Option<NullValue> = value.cast();
assert_eq!(Some(NullValue::NULL_VALUE), null);

Trait Implementations

impl Clone for EnumValueDescriptor

fn clone(&self) -> EnumValueDescriptor

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for EnumValueDescriptor

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

Formats the value using the given formatter.

impl Display for EnumValueDescriptor

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

Formats the value using the given formatter.

impl<'a> From<&'a EnumValueDescriptor> for ReflectValueBox

fn from(v: &'a EnumValueDescriptor) -> Self

Converts to this type from the input type.

impl From<EnumValueDescriptor> for ReflectValueBox

fn from(v: EnumValueDescriptor) -> Self

Converts to this type from the input type.

impl<'a> From<EnumValueDescriptor> for ReflectValueRef<'a>

fn from(v: EnumValueDescriptor) -> Self

Converts to this type from the input type.

impl Hash for EnumValueDescriptor

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 PartialEq for EnumValueDescriptor

fn eq(&self, other: &EnumValueDescriptor) -> 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.
