Struct Args 

pub(super) struct Args<'a> {
    callee: String,
    declared: Option<&'static [Param]>,
    positional: Vec<&'a Expr>,
    positional_taken: usize,
    named: Vec<(&'a str, &'a Expr, Span, bool)>,
}

Fields

callee: String

declared: Option<&'static [Param]>

A built-in’s parameters from its table, which every name the checker asks for must be in, so tools reading the table see the same arguments.

positional: Vec<&'a Expr>

positional_taken: usize

named: Vec<(&'a str, &'a Expr, Span, bool)>

Implementations

impl<'a> Args<'a>

pub(super) fn new( checker: &mut Checker, callee: String, args: &'a [Arg], ) -> Self

callee names what is called in error messages, such as “label”.

pub(super) fn built_in( checker: &mut Checker, name: &str, params: &'static [Param], args: &'a [Arg], ) -> Self

Arguments to the built-in name, whose table entry declares params.

pub(super) fn positional(&mut self) -> Option<&'a Expr>

The next positional argument, if one was given.

pub(super) fn named(&mut self, name: &str) -> Option<&'a Expr>

pub(super) fn param(&mut self, name: &str) -> Option<&'a Expr>

The parameter’s argument, given by position or by name.

pub(super) fn finish(self, checker: &mut Checker)

Reports arguments nothing asked for.
