Struct MultiOracleTrie 

pub struct MultiOracleTrie { /* private fields */ }

Data structure used to store adaptor signature information for numerical outcome DLC with t of n oracles where at least t oracles need to sign the same outcome for the contract to be able to close.

Implementations

impl MultiOracleTrie

pub fn dump(&self) -> MultiOracleTrieDump

Dump the trie information.

pub fn from_dump(dump: MultiOracleTrieDump) -> MultiOracleTrie

Recover a MultiOracleTrie from a dump.

pub fn look_up( &self, paths: &[(usize, Vec<usize>)], ) -> Option<(RangeInfo, Vec<(usize, Vec<usize>)>)>

Lookup for nodes whose path is either equal or a prefix of path.

pub fn new( oracle_numeric_infos: &OracleNumericInfo, threshold: usize, ) -> Result<Self, Error>

Creates a new MultiOracleTrie

Trait Implementations
