Error code E0090

Note: this error code is no longer emitted by the compiler.

You gave too few lifetime arguments. Example:

fn foo<'a: 'b, 'b: 'a>() {} fn main() { foo::<'static>(); // error: wrong number of lifetime arguments: // expected 2, found 1 }

Please check you give the right number of lifetime arguments. Example:

fn foo<'a: 'b, 'b: 'a>() {} fn main() { foo::<'static, 'static>(); }
