Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Implementations

impl Function

pub fn info(self) -> &'static FunctionInfo

The catalog entry.

pub fn name(self) -> &'static str

The name, as written in expressions.

pub fn arity(self) -> (usize, usize)

The fewest and most arguments it takes.

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

The function with this name, in any case. Min and Max are the two-argument forms; with one argument they are aggregates.

pub fn all() -> impl Iterator<Item = Function>

Every built-in function.

Trait Implementations

impl Clone for Function

fn clone(&self) -> Function

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Function

impl Debug for Function

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

Formats the value using the given formatter.

impl Eq for Function

impl Hash for Function

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 for Function

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

Equality operator ==.

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

Inequality operator !=.

impl StructuralPartialEq for Function
