Function nstd_core_str_get 

#[unsafe(no_mangle)]
pub unsafe extern "C" fn nstd_core_str_get(
    str: &NSTDStr,
    pos: NSTDUInt,
) -> NSTDOptionalUnichar

Available on crate feature core only.

Gets the NSTDUnichar at index pos in str.

Note

pos does not refer to the byte index of the character, but the NSTDUnichar index instead.

Parameters:

• const NSTDStr *str - The string slice to index.

• NSTDUInt pos - The index of the character to get.

Returns

NSTDOptionalUnichar chr - The character at index pos, or none on error.

Safety

This operation can cause undefined behavior in the event that str’s data is invalid.

Example

use nstd_sys::core::str::{nstd_core_str_from_raw_cstr, nstd_core_str_get};

let s_str = "🦀🚀🦀!\0";
unsafe {
    let str = nstd_core_str_from_raw_cstr(s_str.as_ptr().cast()).unwrap();
    assert!(nstd_core_str_get(&str, 1).unwrap() == '🚀'.into());
}
