Module sapio_miniscript::descriptor

Output Descriptors

Tools for representing Bitcoin output’s scriptPubKeys as abstract spending policies known as “output descriptors”. These include a Miniscript which describes the actual signing policy, as well as the blockchain format (P2SH, Segwit v0, etc.)

The format represents EC public keys abstractly to allow wallets to replace these with BIP32 paths, pay-to-contract instructions, etc.

Structs

• Bare
  Create a Bare Descriptor. That is descriptor that is not wrapped in sh or wsh. This covers the Pk descriptor
• DescriptorKeyParseError
  Descriptor Key parsing errors
• DescriptorSinglePriv
  A Single Descriptor Secret Key with optional origin information
• DescriptorSinglePub
  A Single Descriptor Key with optional origin information
• DescriptorXKey
  Instance of an extended key with origin and derivation path
• Pkh
  A bare PkH descriptor at top level
• Sh
  A Legacy p2sh Descriptor
• SortedMultiVec
  Contents of a “sortedmulti” descriptor
• Tr
  A taproot descriptor
• Wpkh
  A bare Wpkh descriptor at top level
• Wsh
  A Segwitv0 wsh descriptor

Enums

• ConversionError
  Descriptor key conversion error
• Descriptor
  Script descriptor
• DescriptorPublicKey
  The MiniscriptKey corresponding to Descriptors. This can either be Single public key or a Xpub
• DescriptorSecretKey
  A Secret Key that can be either a single key or an Xprv
• DescriptorType
  Descriptor Type of the descriptor
• ShInner
  Sh Inner
• SinglePubKey
  Single public key without any origin or range information
• TapTree
  A Taproot Tree representation.
• Wildcard
  Whether a descriptor has a wildcard in it
• WshInner
  Wsh Inner

Traits

• DescriptorTrait
  A general trait for Bitcoin descriptor. Offers function for witness cost estimation, script pubkey creation satisfaction using the Satisfier trait.
• InnerXKey
  Trait for “extended key” types like xpub and xprv. Used internally to generalize parsing and handling of bip32::ExtendedPubKey and bip32::ExtendedPrivKey.

Type Aliases

• KeyMap
  Alias type for a map of public key to secret key
