Function hash_update_entry 

Source 
pub unsafe fn hash_update_entry(
    table: *mut HashTable,
    name: *const xmlChar,
    userdata: *mut c_void,
    f: Option<xmlHashDeallocator>,
) -> c_int
Expand description

Update an entry (add or replace).

§UPSTREAM-PARITY

int xmlHashUpdateEntry(xmlHashTablePtr table, const xmlChar *name,
                       void *userdata, xmlHashDeallocator f);

If the key exists, the old payload is deallocated with f and replaced. If the key doesn’t exist, a new entry is added.

Returns 0 on success, -1 on failure.

§SAFETY

Same as hash_add_entry with an additional deallocator.
