pub static UNUSED_ASSIGNMENTS: &Lint
Expand description

The unused_assignments lint detects assignments that will never be read.


let mut x = 5;
x = 6;



Unused assignments may signal a mistake or unfinished code. If the variable is never used after being assigned, then the assignment can be removed. Variables with an underscore prefix such as _x will not trigger this lint.
