Error code E0214

A generic type was described using parentheses rather than angle brackets.

Erroneous code example:

#![allow(unused)] fn main() { let v: Vec(&str) = vec!["foo"]; }

This is not currently supported: v should be defined as Vec<&str>. Parentheses are currently only used with generic types when defining parameters for Fn-family traits.

The previous code example fixed:

#![allow(unused)] fn main() { let v: Vec<&str> = vec!["foo"]; }
