Function elma::trim_string [−] [src]

pub fn trim_string(data: &[u8]) -> Result<String, ElmaError>

Trims trailing bytes after and including null byte.

Examples

As all strings in Elma files are C-strings with padded null-bytes, you can use this function to remove null-bytes and any potential garbage data follwing it and return a String.

let cstring: [u8; 10] = [0x45, 0x6C, 0x6D, 0x61, 0x00, 0x00, 0x00, 0x7E, 0x7E, 0x7E];
let trimmed = elma::trim_string(&cstring).unwrap();
assert_eq!(trimmed, "Elma");
