fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for FieldPresence

fn default() -> Self

impl<'de> Deserialize<'de> for FieldPresence

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl From<i32> for FieldPresence

fn from(value: i32) -> Self

Converts to this type from the input type.
