#[unsafe(no_mangle)]
pub unsafe extern "C" fn nstd_core_str_len(str: &NSTDStr) -> NSTDUInt

Available on crate feature core only.

Returns the number of Unicode characters in a string slice.

Parameters:

• const NSTDStr *str - The string slice.

Returns

NSTDUInt len - The length of the string slice.

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

Example

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

let s_str = "Hello, 🌎!\0";
unsafe {
    let str = nstd_core_str_from_raw_cstr(s_str.as_ptr().cast()).unwrap();
    assert!(nstd_core_str_len(&str) == 9);
}
