Enum sc_service::PruningMode

source · [−]

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.
