Struct ForkchoiceStateTracker

Source 
pub struct ForkchoiceStateTracker { /* private fields */ }
Expand description

The struct that keeps track of the received forkchoice state and their status.

Implementations§

Source§

impl ForkchoiceStateTracker

Source

pub fn set_latest(&mut self, state: ForkchoiceState, status: ForkchoiceStatus)

Sets the latest forkchoice state that we received.

If the status is VALID, we also update the last valid forkchoice state and set the sync_target to None, since we’re now fully synced.

Source

pub fn is_latest_invalid(&self) -> bool

Returns whether the latest received FCU is syncing: ForkchoiceStatus::Invalid

Source

pub fn last_valid_head(&self) -> Option<B256>

Returns the last valid head hash.

Source

pub const fn latest_state(&self) -> Option<ForkchoiceState>

Returns the latest received [ForkchoiceState].

Caution: this can be invalid.

Source

pub const fn last_valid_state(&self) -> Option<ForkchoiceState>

Returns the last valid [ForkchoiceState].

Source

pub fn last_valid_finalized(&self) -> Option<B256>

Returns the last valid finalized hash.

This will return None:

  • If either there is no valid finalized forkchoice state,
  • Or the finalized hash for the latest valid forkchoice state is zero.
Source

pub const fn sync_target_state(&self) -> Option<ForkchoiceState>

Returns the last received ForkchoiceState to which we need to sync.

Source

pub fn sync_target_finalized(&self) -> Option<B256>

Returns the sync target finalized hash.

This will return None:

  • If either there is no sync target forkchoice state,
  • Or the finalized hash for the sync target forkchoice state is zero.
Source

pub const fn is_empty(&self) -> bool

Returns true if no forkchoice state has been received yet.
