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
