Macro str_array

str_array!() { /* proc-macro */ }

Procedural macro proc_strarray::str_array! creates const u8 array from str or byte str literal.

Usage

   // without specified length
   proc_strarray::str_array!(RESULT, "str literal");
   // with specified length
   proc_strarray::str_array!(RESULT2, "string", 6);

Arguments

1. name of created array
2. str or byte str literal
3. (optional) expected length of str literal. Length is only used for length check. It will not trim or extend an array.

Example

    // This code will create const array of u8 named STRU from
    // content of "stru" str literal.
    use proc_strarray::str_array;
    // case 1: automatically determine array length.
    str_array!(STRU, "stru");
    // check if newly created array have length 4 and first character is 's'
    assert_eq!(STRU.len(), 4);
    assert_eq!(STRU[0], 's' as u8);
    // case 2: manually specify expected array length
    str_array!(STRU_len, "stru", 4);
    assert_eq!(STRU_len.len(), 4);
    // case 3: bytestr
    str_array!(STRU_byte, b"stru", 4);
    assert_eq!(STRU_byte.len(), 4);
