Expand description

Trait describing a lookup table for signatures, hash preimages, etc. Every method has a default implementation that simply returns None on every query. Users are expected to override the methods that they have data for.

Provided Methods

Given a public key, look up a signature with that key to_pk_ctx denotes the ToPkCtx required for deriving bitcoin::PublicKey from MiniscriptKey using ToPublicKey. If MiniscriptKey is already is bitcoin::PublicKey, then the context would be NullCtx and [descriptor.DescriptorPublicKeyCtx] if MiniscriptKey is [descriptor.DescriptorPublicKey]

In general, this is defined by generic for the trait ToPublicKey

Given a Pkh, lookup corresponding Pk

Given a keyhash, look up the signature and the associated key Even if signatures for public key Hashes are not available, the users can use this map to provide pkh -> pk mapping which can be useful for dissatisfying pkh. to_pk_ctx denotes the ToPkCtx required for deriving bitcoin::PublicKey from MiniscriptKey using ToPublicKey. If MiniscriptKey is already is bitcoin::PublicKey, then the context would be NullCtx and [descriptor.DescriptorPublicKeyCtx] if MiniscriptKey is [descriptor.DescriptorPublicKey]

In general, this is defined by generic for the trait ToPublicKey

Given a SHA256 hash, look up its preimage

Given a HASH256 hash, look up its preimage

Given a RIPEMD160 hash, look up its preimage

Given a HASH160 hash, look up its preimage

Assert whether an relative locktime is satisfied
