Implementations

impl BuiltinScalarFunction

pub fn supports_zero_argument(&self) -> bool

an allowlist of functions to take zero arguments, so that they will get special treatment while executing.

pub fn volatility(&self) -> Volatility

Returns the Volatility of the builtin function.

Trait Implementations

impl Clone for BuiltinScalarFunction

fn clone(&self) -> BuiltinScalarFunction

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for BuiltinScalarFunction

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

Formats the value using the given formatter.

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 Hash for BuiltinScalarFunction

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)where
    H: Hasher,
    Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq<BuiltinScalarFunction> for BuiltinScalarFunction

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

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
