Struct PruningParams

pub struct PruningParams {
    pub state_pruning: Option<DatabasePruningMode>,
    pub blocks_pruning: DatabasePruningMode,
}

Parameters to define the pruning mode

Fields

state_pruning: Option<DatabasePruningMode>

Specify the state pruning mode.

This mode specifies when the block’s state (ie, storage) should be pruned (ie, removed) from the database. This setting can only be set on the first creation of the database. Every subsequent run will load the pruning mode from the database and will error if the stored mode doesn’t match this CLI value. It is fine to drop this CLI flag for subsequent runs. The only exception is that NUMBER can change between subsequent runs (increasing it will not lead to restoring pruned state).

Possible values:

• archive: Keep the data of all blocks.

• archive-canonical: Keep only the data of finalized blocks.

• NUMBER: Keep the data of the last NUMBER of finalized blocks.

[default: 256]

blocks_pruning: DatabasePruningMode

Specify the blocks pruning mode.

This mode specifies when the block’s body (including justifications) should be pruned (ie, removed) from the database.

Possible values:

• archive: Keep the data of all blocks.

• archive-canonical: Keep only the data of finalized blocks.

• NUMBER: Keep the data of the last NUMBER of finalized blocks.

Implementations

impl Clone for PruningParams

fn clone(&self) -> PruningParams

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PruningParams

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