Struct kernel_NotificationInterfaceCallbacks

#[repr(C)]
pub struct kernel_NotificationInterfaceCallbacks {
    pub user_data: *const c_void,
    pub block_tip: kernel_NotifyBlockTip,
    pub header_tip: kernel_NotifyHeaderTip,
    pub progress: kernel_NotifyProgress,
    pub warning_set: kernel_NotifyWarningSet,
    pub warning_unset: kernel_NotifyWarningUnset,
    pub flush_error: kernel_NotifyFlushError,
    pub fatal_error: kernel_NotifyFatalError,
}

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. Note that this makes it 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: *const c_void

!< Holds a user-defined opaque structure that is passed to the notification callbacks.

block_tip: kernel_NotifyBlockTip

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

header_tip: kernel_NotifyHeaderTip

!< A new best block header was added.

progress: kernel_NotifyProgress

!< Reports on current block synchronization progress.

warning_set: kernel_NotifyWarningSet

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

warning_unset: kernel_NotifyWarningUnset

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

flush_error: kernel_NotifyFlushError

!< An error encountered when flushing data to disk.

fatal_error: kernel_NotifyFatalError

!< A un-recoverable system error encountered by the library.
