pub struct AddedRemovedKeys { /* private fields */ }Expand description
Provides added and removed keys for an account or storage trie.
Used by the crate::proof::ProofRetainer to determine which nodes may be ancestors of newly
added or removed leaves. This information allows for generation of more complete proofs which
include the nodes necessary for adding and removing leaves from the trie.
Implementations§
Source§impl AddedRemovedKeys
impl AddedRemovedKeys
Sourcepub fn with_assume_added(self, assume_added: bool) -> Self
pub fn with_assume_added(self, assume_added: bool) -> Self
Sets the assume_added flag, which can be used instead of insert_added if exact
additions aren’t known and you want to optimistically collect all proofs which might be
necessary.
Sourcepub fn insert_removed(&mut self, key: B256)
pub fn insert_removed(&mut self, key: B256)
Sets the key as being a removed key. This removes the key from the added_keys set if it
was previously inserted into it.
Sourcepub fn remove_removed(&mut self, key: &B256)
pub fn remove_removed(&mut self, key: &B256)
Unsets the key as being a removed key.
Sourcepub fn insert_added(&mut self, key: B256)
pub fn insert_added(&mut self, key: B256)
Sets the key as being an added key. This removes the key from the removed_keys set if it
was previously inserted into it.
Sourcepub fn clear_added(&mut self)
pub fn clear_added(&mut self)
Clears all keys which have been added via insert_added.
Sourcepub fn is_removed(&self, path: &B256) -> bool
pub fn is_removed(&self, path: &B256) -> bool
Returns true if the given key path is marked as removed.
Sourcepub fn is_added(&self, path: &B256) -> bool
pub fn is_added(&self, path: &B256) -> bool
Returns true if the given key path is marked as added.
Sourcepub fn is_prefix_added(&self, prefix: &Nibbles) -> bool
pub fn is_prefix_added(&self, prefix: &Nibbles) -> bool
Returns true if the given path prefix is the prefix of an added key.
Sourcepub fn get_removed_mask(&self, branch_path: &Nibbles) -> TrieMask
pub fn get_removed_mask(&self, branch_path: &Nibbles) -> TrieMask
Returns a mask containing a bit set for each child of the branch which is a prefix of a removed leaf.
