fn default() -> FieldPresence

Returns the “default value” for a type.

impl Enumeration for FieldPresence

fn from_i32(value: i32) -> Option<FieldPresence>

Convert from an i32 wire value to the enum.

fn to_i32(&self) -> i32

Convert the enum to its i32 wire value.

fn proto_name(&self) -> &'static str

The name of this enum variant as it appears in the .proto file.

fn from_proto_name(name: &str) -> Option<FieldPresence>

Look up a variant by its protobuf name string.

impl Eq for FieldPresence

impl Hash for FieldPresence

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

impl PartialEq for FieldPresence

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