Struct Spend 

pub struct Spend { /* private fields */ }

The Bitcoin script interpreter.

Evaluates an unlocking script followed by a locking script, producing a boolean result indicating whether the spend is valid.

Implementations

impl Spend

pub fn new(params: SpendParams) -> Self

Create a new Spend interpreter from the given parameters.

pub fn validate(&mut self) -> Result<bool, ScriptError>

Run full script evaluation: unlocking then locking.

Returns true if the spend is valid (top of stack is truthy after evaluation).

pub fn step(&mut self) -> Result<bool, ScriptError>

Execute a single script chunk.

Returns true if the current script phase is complete, false if more chunks remain.

pub fn is_relaxed(&self) -> bool

Whether the interpreter is in relaxed mode.

Relaxed mode is active when transaction_version > 1 or explicitly overridden. In relaxed mode: clean stack, minimal encoding, NULLDUMMY, low-S, and push-only checks are not enforced.

pub fn set_relaxed_override(&mut self, v: bool)

Override the relaxed mode flag.
