Struct forest_actor::util::SetMultimap [−][src]
pub struct SetMultimap<'a, BS>(_);
SetMultimap is a hamt with values that are also a hamt but are of the set variant. This allows hash sets to be indexable by an address.
Implementations
impl<'a, BS> SetMultimap<'a, BS> where
BS: BlockStore,
[src]
BS: BlockStore,
pub fn new(bs: &'a BS) -> Self
[src]
Initializes a new empty SetMultimap.
pub fn from_root(bs: &'a BS, cid: &Cid) -> Result<Self, Error>
[src]
Initializes a SetMultimap from a root Cid.
pub fn root(&mut self) -> Result<Cid, Error>
[src]
Retrieve root from the SetMultimap.
pub fn put(
&mut self,
key: ChainEpoch,
value: DealID
) -> Result<(), Box<dyn StdError>>
[src]
&mut self,
key: ChainEpoch,
value: DealID
) -> Result<(), Box<dyn StdError>>
Puts the DealID in the hash set of the key.
pub fn put_many(
&mut self,
key: ChainEpoch,
values: &[DealID]
) -> Result<(), Box<dyn StdError>>
[src]
&mut self,
key: ChainEpoch,
values: &[DealID]
) -> Result<(), Box<dyn StdError>>
Puts slice of DealIDs in the hash set of the key.
pub fn get(
&self,
key: ChainEpoch
) -> Result<Option<Set<'a, BS>>, Box<dyn StdError>>
[src]
&self,
key: ChainEpoch
) -> Result<Option<Set<'a, BS>>, Box<dyn StdError>>
Gets the set at the given index of the SetMultimap
pub fn remove(
&mut self,
key: ChainEpoch,
v: DealID
) -> Result<(), Box<dyn StdError>>
[src]
&mut self,
key: ChainEpoch,
v: DealID
) -> Result<(), Box<dyn StdError>>
Removes a DealID from a key hash set.
pub fn remove_all(&mut self, key: ChainEpoch) -> Result<(), Box<dyn StdError>>
[src]
Removes set at index.
pub fn for_each<F>(
&self,
key: ChainEpoch,
f: F
) -> Result<(), Box<dyn StdError>> where
F: FnMut(DealID) -> Result<(), Box<dyn StdError>>,
[src]
&self,
key: ChainEpoch,
f: F
) -> Result<(), Box<dyn StdError>> where
F: FnMut(DealID) -> Result<(), Box<dyn StdError>>,
Iterates through keys and converts them to a DealID to call a function on each.
