Struct ArgumentResult 

pub struct ArgumentResult { /* private fields */ }

Function arguments that have been evaluated

Arguments may be passed either positionally or by name. Positional arguments may not come after named ones.

Implementations

impl ArgumentResult

pub fn get_named<T: Into<Identifier>>( &mut self, val: T, ) -> Option<Spanned<Value>>

Get argument by name

Removes the argument

pub fn get_positional(&mut self, idx: usize) -> Option<Spanned<Value>>

Get a positional argument by 0-indexed position

Replaces argument with Value::Null gravestone

pub fn get<T: Into<Identifier>>( &mut self, position: usize, name: T, ) -> Option<Spanned<Value>>

Get an argument by either name or position

If the named argument does not exist, then the position is checked. Like ArgumentResult::get_named and ArgumentResult::get_positional, this function removes the argument or replaces it with a gravestone

pub fn get_err(&mut self, position: usize, name: &str) -> SassResult<Value>

Like ArgumentResult::get, but returns a result if the argument doesn’t exist

pub const fn span(&self) -> Span

pub fn max_args(&self, max: usize) -> SassResult<()>

Assert that this function has at most max number of args

pub fn default_arg( &mut self, position: usize, name: &'static str, default: Value, ) -> Value

Get an argument by name or position. If the argument does not exist, use the default value provided

Trait Implementations

impl Clone for ArgumentResult

fn clone(&self) -> ArgumentResult

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

Performs copy-assignment from source.

impl Debug for ArgumentResult

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