Struct forest_actor::util::Set [−][src]
pub struct Set<'a, BS>(_);
Set is a Hamt with empty values for the purpose of acting as a hash set.
Implementations

pub fn has(&self, key: &[u8]) -> Result<bool, Error>
[src]
Checks if key exists in the set.
pub fn delete(&mut self, key: &[u8]) -> Result<Option<()>, Error>
[src]
