Trait PruningFilter 

pub trait PruningFilter: Send + Sync {
    // Required method
    fn should_retain(&self, justifications: &Justifications) -> bool;
}

Filter to determine if a block should be excluded from pruning.

Note: This filter only affects block body (and future header) pruning. It does not affect state pruning, which is configured separately.

Required Methods

fn should_retain(&self, justifications: &Justifications) -> bool

Check if a block with the given justifications should be preserved.

Returns true to preserve the block, false to allow pruning.
