value. By default it casts the value to a i64
and passes it to the serialize_i64
method. Read more

Serializes a i64
value.

value. By default it casts the value to a u64
and passes it to the serialize_u64
method. Read more

Serializes a unit variant, otherwise known as a variant with no arguments. Read more
fn serialize_newtype_variant<T>(&mut self, _name: &str, _variant_index: usize, variant: &str, value: T) -> Result<()> where T: Serialize
