}

A struct for holding the kernel notification callbacks. The user data pointer may be used to point to user-defined structures to make processing the notifications easier.

If user_data_destroy is provided, the kernel will automatically call this callback to clean up user_data when the notification interface object is destroyed. If user_data_destroy is NULL, it is the user’s responsibility to ensure that the user_data outlives the kernel objects. Notifications can occur even as kernel objects are deleted, so care has to be taken to ensure safe unwinding.

Fields

user_data: *mut c_void

!< Holds a user-defined opaque structure that is passed to the notification 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_tip: btck_NotifyBlockTip

!< The chain’s tip was updated to the provided block entry.

header_tip: btck_NotifyHeaderTip

!< A new best block header was added.

progress: btck_NotifyProgress

!< Reports on current block synchronization progress.

warning_set: btck_NotifyWarningSet

!< A warning issued by the kernel library during validation.

warning_unset: btck_NotifyWarningUnset

!< A previous condition leading to the issuance of a warning is no longer given.

flush_error: btck_NotifyFlushError

!< An error encountered when flushing data to disk.

fatal_error: btck_NotifyFatalError

!< An unrecoverable system error encountered by the library.
