Enum PruneMode

Source
pub enum PruneMode {
    Full,
    Distance(u64),
    Before(BlockNumber),
}
Expand description

Prune mode.

Variants§

§

Full

Prune all blocks.

§

Distance(u64)

Prune blocks before the head-N block number. In other words, keep last N + 1 blocks.

§

Before(BlockNumber)

Prune blocks before the specified block number. The specified block number is not pruned.

Implementations§

Source§

impl PruneMode

Source

pub const fn bitflag_encoded_bytes() -> usize

Used bytes by [PruneModeFlags]

Source

pub const fn bitflag_unused_bits() -> usize

Unused bits for new fields by [PruneModeFlags]

Source§

impl PruneMode

Source

pub const fn before_inclusive(block_number: BlockNumber) -> Self

Prune blocks up to the specified block number. The specified block number is also pruned.

This acts as PruneMode::Before(block_number + 1).

Source

pub fn prune_target_block( &self, tip: BlockNumber, segment: PruneSegment, purpose: PrunePurpose, ) -> Result<Option<(BlockNumber, Self)>, PruneSegmentError>

Returns block up to which variant pruning needs to be done, inclusive, according to the provided tip.

Source

pub const fn should_prune(&self, block: BlockNumber, tip: BlockNumber) -> bool

Check if target block should be pruned according to the provided prune mode and tip.

Source

pub const fn is_full(&self) -> bool

Returns true if the prune mode is PruneMode::Full.

Source

pub const fn is_distance(&self) -> bool

Returns true if the prune mode is PruneMode::Distance.
