Struct cfxcore::consensus::pivot_hint::PivotHint

impl PivotHint

pub fn new(conf: &PivotHintConfig) -> Result<Self, String>

Creates a new PivotHint instance by loading and validating the pivot hint file.

§Steps

Loads and validates the header
Loads page digests and verifies against provided checksum
Initializes LRU cache for page data

§Arguments

conf - Configuration containing file path and expected checksum

§Errors

File open/read errors
Header parsing errors
Checksum mismatch

pub fn allow_switch( &self, fork_at: u64, me_height: u64, ancestor_hash_at: impl FnOnce(u64) -> H256 ) -> bool

Validates if switching to a target branch is allowed based on pivot hint records.

§Arguments

fork_at - First block height where the current chain and target branch diverge
me_height - Last block height of the target branch
ancestor_hash_at - Callback to retrieve block hash at specified height on target branch

§Returns

Returns whether switching to the fork branch is allowed.

pub fn allow_extend(&self, height: u64, hash: H256) -> bool

pub fn is_active(&self) -> bool
