Module 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
• DefiniteDescriptorKey
  A DescriptorPublicKey without any wildcards.
• DescriptorKeyParseError
  Descriptor Key parsing errors
• DescriptorXKey
  An extended key with origin, derivation path, and wildcard.
• Pkh
  A bare PkH descriptor at top level
• Sh
  A Legacy p2sh Descriptor
• SinglePriv
  A descriptor bitcoin::PrivateKey with optional origin information.
• SinglePub
  A descriptor SinglePubKey with optional origin information.
• 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 descriptor pubkey, either a single pubkey or an xpub.
• DescriptorSecretKey
  The descriptor secret key, either a single private 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

• InnerXKey
  Trait for “extended key” types like xpub and xprv. Used internally to generalize parsing and handling of bip32::ExtendedPubKey and bip32::ExtendedPrivKey.

Type Definitions

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