rust - What is the idiomatic way to write a for loop without using the iterator value? -


assuming want finite loop using range:

let mut x: i32 = 0; in 1..10 {     x += 1; }

the compiler spit out warning:

warning: unused variable: `i`, #[warn(unused_variables)] on default in 1..10 {     ^

is there more idiomatic way write won't make compiler complain?

you can write _ pattern, meaning “discard value”:

let mut x: i32 = 0; _ in 1..10 {     x += 1; }
