Struct CallSignature 

pub struct CallSignature { /* private fields */ }

A language-neutral call signature.

Positional parameters are filled in declaration order. Named parameters are addressable only by name. Each unmatched partition is independently either prohibited or collected into a variadic binding.

Implementations

impl CallSignature

pub fn new() -> Self

Creates an empty signature which prohibits all arguments.

pub fn with_positional(self, parameters: Vec<CallParameter>) -> Self

Replaces the ordered positional partition.

pub fn with_named(self, parameters: Vec<CallParameter>) -> Self

Replaces the named partition.

pub fn with_positional_remainder(self, remainder: Remainder) -> Self

Selects how unmatched positional arguments are handled.

pub fn with_named_remainder(self, remainder: Remainder) -> Self

Selects how unmatched named arguments are handled.

pub fn bind( &self, arguments: impl IntoIterator<Item = CallArgument>, ) -> Result<BoundCall>

Validates the declaration and binds a call without invoking its body.
