[−][src]Trait contrail::storage::StorageMode

pub trait StorageMode: Debug + Default {
    fn builder_mut(builder: &mut TrailBuilder) -> &mut MemoryBuilder;

    fn memory(trail: &Trail) -> &Memory;

    fn memory_mut(trail: &mut Trail) -> &mut Memory;
}

Representation of how something is stored on the trail.

Objects can be stored on the trail in backtrackable or non-backtrackable memory, represented by Backtrackable and NonBacktrackable, respectively. Both of these structs implement StorageMode. See the documentation for Trail for the difference between backtrackable and non-backtrackable storage.

Returns the associated MemoryBuilder from a TrailBuilder.

fn memory(trail: &Trail) -> &Memory
