Struct CallExpr 

pub struct CallExpr(/* private fields */);

Implementations

impl CallExpr

pub fn arg_list(&self) -> Option<ArgList>

pub fn callee_token(&self) -> Option<SyntaxToken<RLanguage>>

The callee name token — the IDENT/STRING immediately preceding the argument list, when the function being called is a simple name (foo(…), `+`(…)) or a namespace-qualified name (pkg::fn(…), where the token is the fn member). Returns None for a genuinely computed callee ((g())(…), x$f(…)).

pub fn callee_name(&self) -> Option<SmolStr>

The callee name (foo in foo(…), + in `+`(…)), unquoted, when the callee is a simple name. None for a computed callee.

pub fn base(&self) -> Option<SyntaxElement<RLanguage>>

The callee element — everything before the argument list’s (. Generalizes CallExpr::callee_token to the computed-callee case ((g())(…), x$f(…)), where it returns the callee node instead of a name token.
