Implementations§

impl ScalarFunction

pub fn from_identifier(name: &str) -> Option<Self>

Trait Implementations§

impl Clone for ScalarFunction

fn clone(&self) -> ScalarFunction

Returns a duplicate of the value. Read more

1.0.0 · Source§

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

Performs copy-assignment from source. Read more

impl Debug for ScalarFunction

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

Formats the value using the given formatter. Read more

impl PartialEq for ScalarFunction

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

Tests for self and other values to be equal, and is used by ==.

1.0.0 · Source§

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

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