Struct EnumDescriptor

pub struct EnumDescriptor { /* private fields */ }

Dynamic representation of enum type.

Can be used in reflective operations.

Implementations

impl EnumDescriptor

pub fn proto(&self) -> &EnumDescriptorProto

Descriptor objects which defined this enum.

pub fn name(&self) -> &str

Enum name as given in .proto file

pub fn full_name(&self) -> &str

Fully qualified protobuf name of enum

pub fn name_to_package(&self) -> &str

Name relative to the package where the message is declared.

pub fn for_type<E: EnumFull>() -> EnumDescriptor

Get EnumDescriptor object for given enum type

pub fn enclosing_message(&self) -> Option<MessageDescriptor>

Get a message containing this message, or None if this message is declared at file level.

pub fn values<'a>(&'a self) -> impl Iterator<Item = EnumValueDescriptor> + 'a

This enum values

pub fn value_by_name(&self, name: &str) -> Option<EnumValueDescriptor>

Find enum variant by name

pub fn value_by_number(&self, number: i32) -> Option<EnumValueDescriptor>

Find enum variant by number

pub fn value_by_index(&self, index: usize) -> EnumValueDescriptor

Get enum variant by index (as declared in .proto file).

pub fn default_value(&self) -> EnumValueDescriptor

Default enum value (first variant).

pub fn value_by_number_or_default(&self, number: i32) -> EnumValueDescriptor

Find enum variant by number or return default (first) enum value

pub fn is<E: Enum>(&self) -> bool

Check if this enum descriptor corresponds given enum type

let descriptor: EnumDescriptor = Label::enum_descriptor();

assert!(descriptor.is::<Label>())
}

Trait Implementations

impl Clone for EnumDescriptor

fn clone(&self) -> EnumDescriptor

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for EnumDescriptor

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

Formats the value using the given formatter.

impl Display for EnumDescriptor

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

Formats the value using the given formatter.

impl Hash for EnumDescriptor

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 EnumDescriptor

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