Trait PsbtInputExt 

pub trait PsbtInputExt {
    // Required method
    fn update_with_descriptor_unchecked(
        &mut self,
        descriptor: &Descriptor<DefiniteDescriptorKey>,
    ) -> Result<Descriptor<PublicKey>, ConversionError>;
}

Extension trait for PSBT inputs

Required Methods

fn update_with_descriptor_unchecked( &mut self, descriptor: &Descriptor<DefiniteDescriptorKey>, ) -> Result<Descriptor<PublicKey>, ConversionError>

Given the descriptor for a utxo being spent populate the PSBT input’s fields so it can be signed.

If the descriptor contains wildcards or otherwise cannot be transformed into a concrete descriptor an error will be returned. The descriptor can (and should) have extended keys in it so PSBT fields like bip32_derivation and tap_key_origins can be populated.

Note that his method doesn’t check that the witness_utxo or non_witness_utxo is consistent with the descriptor. To do that see update_input_with_descriptor.

Return value

For convenience, this returns the concrete descriptor that is computed internally to fill out the PSBT input fields. This can be used to manually check that the script_pubkey in witness_utxo and/or non_witness_utxo is consistent with the descriptor.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
