fn expand( &self, pos: i32, provider: &SigningProvider, output_scripts: &mut Vec<Script>, out: &mut FlatSigningProvider, write_cache: Option<*mut DescriptorCache> ) -> bool

| Expand a descriptor at a specified position. | | ———– | @param[in] pos | | The position at which to expand the descriptor. | If IsRange() is false, this is ignored. | ––––– | @param[in] provider | | The provider to query for private keys | in case of hardened derivation. | ––––– | @param[out] output_scripts | | The expanded scriptPubKeys. | ––––– | @param[out] out | | Scripts and public keys necessary for | solving the expanded scriptPubKeys | (may be equal to provider). | ––––– | @param[out] write_cache | | Cache data necessary to evaluate the | descriptor at this point without access | to private keys. |
