Module bdk::descriptor::policy[][src]

Expand description

Descriptor policy

This module implements the logic to extract and represent the spending policies of a descriptor in a more human-readable format.

This is an EXPERIMENTAL feature, API and other major changes are expected.


use bdk::descriptor::policy::BuildSatisfaction;
let secp = Secp256k1::new();
let desc = "wsh(and_v(v:pk(cV3oCth6zxZ1UVsHLnGothsWNsaoxRhC6aeNi5VbSdFpwUkgkEci),or_d(pk(cVMTy7uebJgvFaSBwcgvwk8qn8xSLc97dKow4MBetjrrahZoimm2),older(12960))))";

let (extended_desc, key_map) = ExtendedDescriptor::parse_descriptor(&secp, desc)?;
println!("{:?}", extended_desc);

let signers = Arc::new(key_map.into());
let policy = extended_desc.extract_policy(&signers, BuildSatisfaction::None, &secp)?;
println!("policy: {}", serde_json::to_string(&policy)?);
