impl Oneof for __Self

where (): ForOverwrite<general_packed, ListValue> + ForOverwrite<general_packed, String> + ForOverwrite<general_packed, StructValue> + ForOverwrite<general_packed, bool> + ForOverwrite<general_packed, f64> + ForOverwrite<general_packed, i64> + ForOverwrite<general_packed, u64> + ValueEncoder<general_packed, ListValue> + ValueEncoder<general_packed, String> + ValueEncoder<general_packed, StructValue> + ValueEncoder<general_packed, bool> + ValueEncoder<general_packed, f64> + ValueEncoder<general_packed, i64> + ValueEncoder<general_packed, u64>,

const FIELD_TAGS: &'static [u32]

fn empty() -> Self

Returns a new empty oneof.

fn is_empty(&self) -> bool

Returns whether the oneof is in the empty variant.

fn clear(&mut self)

Resets the oneof to the empty variant.

fn oneof_encode<__B: BufMut + ?Sized>(&self, buf: &mut __B, tw: &mut TagWriter)

Encodes the fields of the oneof into the given buffer.

impl PartialEq for Value

fn eq(&self, other: &Value) -> bool
