Function nstd_string_from_str 

#[unsafe(no_mangle)]
pub unsafe extern "C" fn nstd_string_from_str<'a>(
    allocator: &'a NSTDAllocator,
    str: &NSTDStr,
) -> NSTDOptionalString<'a>

Available on crate feature string only.

Creates an owned version of an unowned string slice.

Parameters:

• const NSTDAllocator *allocator - The memory allocator.

• const NSTDStr *str - The unowned string slice.

Returns

NSTDOptionalString string - The new owned version of str on success, or an uninitialized “none” variant if allocating fails.

Safety

The caller of this function must ensure that str’s data is valid for reads.

Example

use nstd_sys::{
    alloc::NSTD_ALLOCATOR, core::str::nstd_core_str_from_raw_cstr, string::nstd_string_from_str,
};

unsafe {
    let str = nstd_core_str_from_raw_cstr("Hello, world!\0".as_ptr().cast()).unwrap();
    let string = nstd_string_from_str(&NSTD_ALLOCATOR, &str);
}
