Fields

load_pre_key: Option<unsafe extern "C" fn(record: *mut *mut signal_buffer, pre_key_id: u32, user_data: *mut c_void) -> c_int>

Load a local serialized PreKey record.

@param record pointer to a newly allocated buffer containing the record, if found. Unset if no record was found. The Signal Protocol library is responsible for freeing this buffer. @param pre_key_id the ID of the local serialized PreKey record @retval SG_SUCCESS if the key was found @retval SG_ERR_INVALID_KEY_ID if the key could not be found

store_pre_key: Option<unsafe extern "C" fn(pre_key_id: u32, record: *mut u8, record_len: usize, user_data: *mut c_void) -> c_int>

Store a local serialized PreKey record.

@param pre_key_id the ID of the PreKey record to store. @param record pointer to a buffer containing the serialized record @param record_len length of the serialized record @return 0 on success, negative on failure

contains_pre_key: Option<unsafe extern "C" fn(pre_key_id: u32, user_data: *mut c_void) -> c_int>

Determine whether there is a committed PreKey record matching the provided ID.

@param pre_key_id A PreKey record ID. @return 1 if the store has a record for the PreKey ID, 0 otherwise

remove_pre_key: Option<unsafe extern "C" fn(pre_key_id: u32, user_data: *mut c_void) -> c_int>

Delete a PreKey record from local storage.

@param pre_key_id The ID of the PreKey record to remove. @return 0 on success, negative on failure

destroy_func: Option<unsafe extern "C" fn(user_data: *mut c_void)>

Function called to perform cleanup when the data store context is being destroyed.

user_data: *mut c_void

User data pointer
