Struct rsass::SassFunction

pub struct SassFunction { /* fields omitted */ }

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 SassFunction

pub fn builtin(
    args: Vec<(String, Value)>,
    is_varargs: bool,
    body: Arc<dyn Fn(&dyn Scope) -> Result<Value, Error> + Send + Sync>
) -> Self

Create a new SassFunction from a rust implementation.

pub fn new(args: FormalArgs, body: Vec<Item>) -> Self

Create a new SassFunction from a scss implementation.

pub fn call(&self, scope: &dyn Scope, args: &CallArgs) -> Result<Value, Error>

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

Trait Implementations

impl Clone for SassFunction

fn clone(&self) -> SassFunction

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for SassFunction

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

Formats the value using the given formatter.

impl Eq for SassFunction

impl Ord for SassFunction

fn cmp(&self, other: &SassFunction) -> Ordering

This method returns an Ordering between self and other.

#[must_use]fn max(self, other: Self) -> Self

Compares and returns the maximum of two values.

#[must_use]fn min(self, other: Self) -> Self

Compares and returns the minimum of two values.

#[must_use]fn clamp(self, min: Self, max: Self) -> Self

🔬 This is a nightly-only experimental API. (clamp)

Restrict a value to a certain interval.

impl PartialEq<SassFunction> for SassFunction

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

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

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

This method tests for !=.

impl PartialOrd<SassFunction> for SassFunction

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

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

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

This method tests less than (for self and other) and is used by the < operator.

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

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

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

This method tests greater than (for self and other) and is used by the > operator.

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

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