Struct Args

pub struct Args {
    pub span: Span,
    pub items: EcoVec<Arg>,
}

Fields

span: Span

items: EcoVec<Arg>

Implementations

impl Args

pub fn new<T: IntoValue>(span: Span, items: impl IntoIterator<Item = T>) -> Self

pub fn insert(&mut self, index: i32, span: Span, value: Value)

pub fn push(&mut self, span: Span, value: Value)

pub fn spanned(self, span: Span) -> Args

pub fn eat<T>(&mut self) -> SourceResult<Option<T>>

where T: FromValue<Spanned<Value>>,

pub fn expect<T>(&mut self, what: &str) -> SourceResult<T>

where T: FromValue<Spanned<Value>>,

pub fn named<T>(&mut self, name: &str) -> SourceResult<Option<T>>

where T: FromValue<Spanned<Value>>,

Remove all args with the given name and return the last or an error if the conversion fails.

If no such arg exists, then Ok(None) is returned

pub fn all<T>(&mut self) -> SourceResult<Vec<T>>

where T: FromValue<Spanned<Value>>,

Find and consume all castable positional arguments

pub fn take(&mut self) -> Self

Take out all arguments into a new instance.

pub fn finish(self) -> SourceResult<()>

Return an “unexpected argument” error if there is any remaining argument.

Performs copy-assignment from source.

impl Debug for Args

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