Performs copy-assignment from source.

impl Debug for FunctionExpr

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for FunctionExpr

fn deserialize<__D>( __deserializer: __D ) -> Result<FunctionExpr, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for FunctionExpr

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

Formats the value using the given formatter.

impl From<BinaryFunction> for FunctionExpr

fn from(b: BinaryFunction) -> FunctionExpr
