convert string to i32 rust
To convert a string to an i32 in Rust, you can use the parse
method provided by the str
type, followed by the unwrap
method to extract the resulting value. Here's an example:
let my_string = "42";
let my_integer: i32 = my_string.parse().unwrap();
This code assumes that my_string
contains a valid representation of an i32 value. If the string cannot be parsed as an i32, the parse
method will return a Result
type, which you can handle accordingly.
