Trait protobuf::Enum

pub trait Enum: Eq + Sized + Copy + Debug + Default + Send + Sync + 'static {
    const NAME: &'static str;

    fn value(&self) -> i32;
    fn from_i32(v: i32) -> Option<Self>;
    fn values() -> &'static [Self];
}

Trait implemented by all protobuf enum types.

Additionally, generated enums also implement EnumFull trait, which provides access to reflection.

Associated Constants

const NAME: &'static str

Enum name as specified in .proto file.

There’s full reflection when non-lite runtime code generation is used, and enums implement EnumFull trait. This operation is for lite runtime.

Required methods

fn value(&self) -> i32

Get enum i32 value.

fn from_i32(v: i32) -> Option<Self>

Try to create an enum from i32 value. Return None if value is unknown.

fn values() -> &'static [Self]

Get all enum values for enum type.
