Error code E0453
A lint check attribute was overruled by a forbid
directive set as an
attribute on an enclosing scope, or on the command line with the -F
option.
Example of erroneous code:
#![forbid(non_snake_case)] #[allow(non_snake_case)] fn main() { // error: allow(non_snake_case) incompatible with previous forbid let MyNumber = 2; }
The forbid
lint setting, like deny
, turns the corresponding compiler
warning into a hard error. Unlike deny
, forbid
prevents itself from being
overridden by inner attributes.
If you're sure you want to override the lint check, you can change forbid
to
deny
(or use -D
instead of -F
if the forbid
setting was given as a
command-line option) to allow the inner lint check attribute:
#![deny(non_snake_case)] #[allow(non_snake_case)] fn main() { let MyNumber = 2; // ok! }
Otherwise, edit the code to pass the lint check, and remove the overruled attribute:
#![forbid(non_snake_case)] fn main() { let my_number = 2; }
