Struct sc_state_db::Constraints

source · [−]

pub struct Constraints {
    pub max_blocks: Option<u32>,
    pub max_mem: Option<usize>,
}

Expand description

Pruning constraints. If none are specified pruning is

Fields

max_blocks: Option<u32>

Maximum blocks. Defaults to 0 when unspecified, effectively keeping only non-canonical states.

max_mem: Option<usize>

Maximum memory in the pruning overlay.
