Struct protobuf::ProtobufEnumOrUnknown

#[repr(transparent)]
pub struct ProtobufEnumOrUnknown<E> { /* fields omitted */ }

Protobuf enums with possibly unknown values are preserved in this struct.

Implementations

impl<E> ProtobufEnumOrUnknown<E>

pub const fn from_i32(value: i32) -> ProtobufEnumOrUnknown<E>

Construct from any i32 value.

Note passed value is not required to be a valid enum value.

impl<E: ProtobufEnum> ProtobufEnumOrUnknown<E>

pub fn new(e: E) -> ProtobufEnumOrUnknown<E>

Construct from typed enum

pub fn value(&self) -> i32

Get contained i32 value of enum

pub fn enum_value(&self) -> Result<E, i32>

Get i32 value as typed enum. Return None is value is unknown.

pub fn unwrap(&self) -> E

Get contained enum, panic if value is unknown.

pub fn enum_value_or_default(&self) -> E

Get i32 value as typed enum. Return default enum value (first value) if value is unknown.

pub fn enum_value_or(&self, map_unknown: E) -> E

Get i32 value as typed enum. Return given enum value if value is unknown.

pub fn enum_descriptor_static() -> EnumDescriptor

Get enum descriptor by type.
