Enum sc_state_db::PruningMode

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

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

impl PruningMode

pub fn blocks_pruning(n: u32) -> PruningMode

Create a mode that keeps given number of blocks.

pub fn is_archive(&self) -> bool

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

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

Returns the pruning mode

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

Trait Implementations

impl Clone for PruningMode

fn clone(&self) -> PruningMode

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for PruningMode

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for PruningMode

fn default() -> Self

Returns the “default value” for a type.

impl PartialEq<PruningMode> for PruningMode

fn eq(&self, other: &PruningMode) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
