Struct btck_ValidationInterfaceCallbacks 

#[repr(C)]
pub struct btck_ValidationInterfaceCallbacks {
    pub user_data: *mut c_void,
    pub user_data_destroy: btck_DestroyCallback,
    pub block_checked: btck_ValidationInterfaceBlockChecked,
    pub pow_valid_block: btck_ValidationInterfacePoWValidBlock,
    pub block_connected: btck_ValidationInterfaceBlockConnected,
    pub block_disconnected: btck_ValidationInterfaceBlockDisconnected,
}

Holds the validation interface callbacks. The user data pointer may be used to point to user-defined structures to make processing the validation callbacks easier. Note that these callbacks block any further validation execution when they are called.

Fields

user_data: *mut c_void

!< Holds a user-defined opaque structure that is passed to the validation !< interface callbacks. If user_data_destroy is also defined ownership of the !< user_data is passed to the created context options and subsequently context.

user_data_destroy: btck_DestroyCallback

!< Frees the provided user data structure.

block_checked: btck_ValidationInterfaceBlockChecked

!< Called when a new block has been fully validated. Contains the !< result of its validation.

pow_valid_block: btck_ValidationInterfacePoWValidBlock

!< Called when a new block extends the header chain and has a valid transaction !< and segwit merkle root.

block_connected: btck_ValidationInterfaceBlockConnected

!< Called when a block is valid and has now been connected to the best chain.

block_disconnected: btck_ValidationInterfaceBlockDisconnected

!< Called during a re-org when a block has been removed from the best chain.
