pub enum PruningMode {
    Constrained(Constraints),
    ArchiveAll,
    ArchiveCanonical,
}
Expand description

Pruning mode.

Variants§

§

Constrained(Constraints)

Maintain a pruning window.

§

ArchiveAll

No pruning. Canonicalization is a no-op.

§

ArchiveCanonical

Canonicalization discards non-canonical nodes. All the canonical nodes are kept in the DB.

Implementations§

source§

impl PruningMode

source

pub fn blocks_pruning(n: u32) -> PruningMode

Create a mode that keeps given number of blocks.

source

pub fn is_archive(&self) -> bool

Is this an archive (either ArchiveAll or ArchiveCanonical) pruning mode?

source

pub fn id(&self) -> &[u8]

Returns the pruning mode

source

pub fn from_id(id: &[u8]) -> Option<Self>
