Struct grovedb_merk::tree::PanicSource

pub struct PanicSource {}

Expand description

A source of data which panics when called. Useful when creating a store which always keeps the state in memory.

Trait Implementations§

impl Clone for PanicSource

impl Fetch for PanicSource

fn fetch( &self, _link: &Link, _value_defined_cost_fn: Option<&impl Fn(&[u8], &GroveVersion) -> Option<ValueDefinedCostType>>, _grove_version: &GroveVersion, ) -> CostResult<TreeNode, Error>

Called when the tree needs to fetch a node with the given Link. The link value will always be a Link::Reference variant.
