Struct Function

pub struct Function { /* private fields */ }

A function that can be called from a sass value.

The function can be either “builtin” (implemented in rust) or “user defined” (implemented in scss).

Implementations

impl Function

pub fn get_builtin(name: &Name) -> Option<&'static Self>

Get a built-in function by name.

pub fn builtin( module: &str, name: &Name, args: FormalArgs, body: Arc<dyn Fn(&ResolvedArgs) -> Result<Value, CallError> + Send + Sync>, ) -> Self

Create a new Function from a rust implementation.

Note: This does not expose the function in any scope, it just creates it.

pub fn call(&self, call: Call) -> Result<Value, CallError>

Call the function from a given scope and with a given set of arguments.

Trait Implementations

impl Clone for Function

fn clone(&self) -> Function

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Function

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

Formats the value using the given formatter.

impl From<Closure> for Function

fn from(c: Closure) -> Self

Converts to this type from the input type.

impl PartialEq for Function

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

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

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

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

impl PartialOrd for Function

fn partial_cmp(&self, other: &Function) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
