Private Function

std.zig.Parse.expectParamDecl

fn expectParamDecl(p: *Parse) !?Node.Index

This function can return null nodes and then still return nodes afterwards, such as in the case of anytype and .... Caller must look for rparen to find out when there are no more param decls left.

Params

p: *Parse
