Function yrs::yxmltext_insert

#[no_mangle]
pub unsafe extern "C" fn yxmltext_insert(
    txt: *const XmlText, 
    txn: *mut Transaction, 
    index: c_int, 
    str: *const c_char
)

Inserts a null-terminated UTF-8 encoded string a a given index. index value must be between 0 and a length of a YXmlText (inclusive, accordingly to yxmltext_len return value), otherwise this function will panic.

A str parameter must be a null-terminated UTF-8 encoded string. This function doesn’t take ownership over a passed value - it will be copied and therefore a string parameter must be released by the caller.
