Struct themelio_stf::melvm::Covenant
source · Expand description
A MelVM covenant. Essentially, given a transaction that attempts to spend it, it either allows the transaction through or doesn’t.

Implementations
sourceimpl Covenant
impl Covenant
sourcepub fn from_ops(ops: &[OpCode]) -> Result<Self, EncodeError>
pub fn from_ops(ops: &[OpCode]) -> Result<Self, EncodeError>
Create a Covenant from a slice of OpCodes.
sourcepub fn check(&self, tx: &Transaction, env: CovenantEnv) -> bool
pub fn check(&self, tx: &Transaction, env: CovenantEnv) -> bool
Checks a transaction, returning whether or not the transaction is valid.
The caller must also pass in the CoinID and CoinDataHeight corresponding to the coin that’s being spent, as well as the Header of the previous block (if this transaction is trying to go into block N, then the header of block N-1). This allows the covenant to access (a commitment to) its execution environment, allowing constructs like timelock contracts and colored-coin-like systems.
sourcepub fn check_opt_env(&self, tx: &Transaction, env: Option<CovenantEnv>) -> bool
pub fn check_opt_env(&self, tx: &Transaction, env: Option<CovenantEnv>) -> bool
Execute a transaction in a CovenantEnv to completion and return whether the covenant succeeded.
sourcepub fn debug_run_without_transaction(&self, args: &[Value]) -> bool
pub fn debug_run_without_transaction(&self, args: &[Value]) -> bool
Runs to the end, with respect to a manually instantiated initial heap. This is for testing, when we do not have a transaction.
sourcepub fn debug_run_outputting_stack_and_heap(
&self,
args: &[Value]
) -> Option<(Vec<Value>, HashMap<u16, Value>)>
pub fn debug_run_outputting_stack_and_heap(
&self,
args: &[Value]
) -> Option<(Vec<Value>, HashMap<u16, Value>)>
Runs to the end, with respect to a manually instantiated initial heap. This is for testing, when we do not have a transaction. This method outputs a tuple containing the stack and the heap.
sourcepub fn std_ed25519_pk_legacy(pk: Ed25519PK) -> Self
pub fn std_ed25519_pk_legacy(pk: Ed25519PK) -> Self
Returns a legacy ed25519 signature checking covenant, which checks the first signature.
sourcepub fn std_ed25519_pk_new(pk: Ed25519PK) -> Self
pub fn std_ed25519_pk_new(pk: Ed25519PK) -> Self
Returns a new ed25519 signature checking covenant, which checks the nth signature when spent as the nth input.
pub fn always_true() -> Self
pub fn weight(&self) -> Result<u128, DecodeError>
