impl ScriptContext for Segwitv0

§

type Key = PublicKey

The consensus key associated with the type. Must be a parseable key
§

fn check_terminal_non_malleable<Pk>( _frag: &Terminal<Pk, Segwitv0> ) -> Result<(), ScriptContextError>
where Pk: MiniscriptKey,

Depending on ScriptContext, fragments can be malleable. For Example, under Legacy context, PkH is malleable because it is possible to estimate the cost of satisfaction because of compressed keys This is currently only used in compiler code for removing malleable compilations. This does NOT recursively check if the children of the fragment are valid or not. Since the compilation proceeds in a leaf to root fashion, a recursive check is unnecessary.
§

fn check_pk<Pk>(pk: &Pk) -> Result<(), ScriptContextError>
where Pk: MiniscriptKey,

Each context has slightly different rules on what Pks are allowed in descriptors Legacy/Bare does not allow x_only keys Segwit does not allow uncompressed keys and x_only keys Tapscript does not allow uncompressed keys
§

fn check_witness(witness: &[Vec<u8>]) -> Result<(), ScriptContextError>

Check whether the given satisfaction is valid under the ScriptContext For example, segwit satisfactions may fail if the witness len is more 3600 or number of stack elements are more than 100.
§

fn check_global_consensus_validity<Pk>( ms: &Miniscript<Pk, Segwitv0> ) -> Result<(), ScriptContextError>
where Pk: MiniscriptKey,

Depending on script Context, some of the Terminals might not be valid under the current consensus rules. Or some of the script resource limits may have been exceeded. These miniscripts would never be accepted by the Bitcoin network and hence it is safe to discard them For example, in Segwit Context with MiniscriptKey as bitcoin::PublicKey uncompressed public keys are non-standard and thus invalid. In LegacyP2SH context, scripts above 520 bytes are invalid. Post Tapscript upgrade, this would have to consider other nodes. This does NOT recursively check the miniscript fragments.
§

fn check_local_consensus_validity<Pk>( ms: &Miniscript<Pk, Segwitv0> ) -> Result<(), ScriptContextError>
where Pk: MiniscriptKey,

Consensus rules at the Miniscript satisfaction time. It is possible that some paths of miniscript may exceed resource limits and our current satisfier and lifting analysis would not work correctly. For example, satisfaction path(Legacy/Segwitv0) may require more than 201 opcodes.
§

fn check_global_policy_validity<Pk>( ms: &Miniscript<Pk, Segwitv0> ) -> Result<(), ScriptContextError>
where Pk: MiniscriptKey,

Depending on script Context, some of the script resource limits may have been exceeded under the current bitcoin core policy rules These miniscripts would never be accepted by the Bitcoin network and hence it is safe to discard them. (unless explicitly disabled by non-standard flag) For example, in Segwit Context with MiniscriptKey as bitcoin::PublicKey scripts over 3600 bytes are invalid. Post Tapscript upgrade, this would have to consider other nodes. This does NOT recursively check the miniscript fragments.
§

fn check_local_policy_validity<Pk>( ms: &Miniscript<Pk, Segwitv0> ) -> Result<(), ScriptContextError>
where Pk: MiniscriptKey,

Policy rules at the Miniscript satisfaction time. It is possible that some paths of miniscript may exceed resource limits and our current satisfier and lifting analysis would not work correctly. For example, satisfaction path in Legacy context scriptSig more than 1650 bytes
§

fn max_satisfaction_size<Pk>(ms: &Miniscript<Pk, Segwitv0>) -> Option<usize>
where Pk: MiniscriptKey,

Depending on script context, the size of a satifaction witness may slightly differ.
§

fn pk_len<Pk>(_pk: &Pk) -> usize
where Pk: MiniscriptKey,

Get the len of public key when serialized based on context Note that this includes the serialization prefix. Returns 34/66 for Bare/Legacy based on key compressedness 34 for Segwitv0, 33 for Tap
§

fn name_str() -> &'static str

Local helper function to display error messages with context
§

fn sig_type() -> SigType

The type of signature required for satisfaction
§

fn check_global_validity<Pk>( ms: &Miniscript<Pk, Self> ) -> Result<(), ScriptContextError>
where Pk: MiniscriptKey,

Check the consensus + policy(if not disabled) rules that are not based satisfaction
§

fn check_local_validity<Pk>( ms: &Miniscript<Pk, Self> ) -> Result<(), ScriptContextError>
where Pk: MiniscriptKey,

Check the consensus + policy(if not disabled) rules including the ones for satisfaction
§

where Pk: MiniscriptKey,

§

fn other_top_level_checks<Pk>(_ms: &Miniscript<Pk, Self>) -> Result<(), Error>
where Pk: MiniscriptKey,

§
