impl Display for BuiltinScalarFunction

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

Formats the value using the given formatter.

impl FromStr for BuiltinScalarFunction

type Err = DataFusionError

The associated error which can be returned from parsing.

fn from_str(name: &str) -> Result<BuiltinScalarFunction>

Parses a string s to return a value of this type.

impl PartialEq<BuiltinScalarFunction> for BuiltinScalarFunction

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