Struct MultiOracleTrieWithDiff 

pub struct MultiOracleTrieWithDiff {
    pub multi_trie: MultiTrie<RangeInfo>,
    pub oracle_numeric_infos: OracleNumericInfo,
}

Data structure used to store adaptor signature information for numerical outcome DLC with multiple oracles where some difference between the outcomes of each oracle can be supported.

Fields

multi_trie: MultiTrie<RangeInfo>

The underlying trie of trie

oracle_numeric_infos: OracleNumericInfo

Information on the numeric representation used by each oracle.
