An abstraction over our internal hashes, rb trees, and prefix tries.
This is useful where the data type being inserted into the tree is user controlled, and so we need to pick the most efficient structure for a given data type dynamically at runtime.
| [in] | ctx | to bind the htrie's lifetime to. |
| [in] | type | One of:
|
| [in] | hash_data | Used by FR_HTRIE_HASH to convert the data into a 32bit integer used for binning. |
| [in] | cmp_data | Used to determine exact matched. |
| [in] | get_key | Used by the prefix trie to extract a key from the data. |
| [in] | free_data | The callback used to free the data if it is deleted or replaced. May be NULL in which case data will not be freed for these operations. |
