Function nstd_sys::string::nstd_string_push_str

#[no_mangle]
pub unsafe extern "C" fn nstd_string_push_str(
    string: &mut NSTDString<'_>,
    str: &NSTDStr
) -> NSTDAllocError

Available on crate feature string only.

Appends a string slice to the end of a string.

Parameters:

• NSTDString *string - The string.

• const NSTDStr *str - The string slice to append to the end of string.

Returns

NSTDAllocError errc - The allocation operation error code.

Safety

This function will cause undefined behavior in the case where str’s data is no longer valid.

Example

use nstd_sys::{
    alloc::{NSTDAllocError::NSTD_ALLOC_ERROR_NONE, NSTD_ALLOCATOR},
    core::str::nstd_core_str_from_raw_cstr,
    string::{nstd_string_new, nstd_string_push_str},
};

unsafe {
    let str = nstd_core_str_from_raw_cstr("Hello, 🌎!\0".as_ptr().cast()).unwrap();
    let mut string = nstd_string_new(&NSTD_ALLOCATOR);
    assert!(nstd_string_push_str(&mut string, &str) == NSTD_ALLOC_ERROR_NONE);
}
