Implementations

impl<Pk: MiniscriptKey, Ctx: ScriptContext> Terminal<Pk, Ctx>

pub fn encode(&self, builder: Builder) -> Builder where
    Pk: ToPublicKey, 

Encode the element as a fragment of Bitcoin Script. The inverse function, from Script to an AST element, is implemented in the parse module.

pub fn script_size(&self) -> usize

Size, in bytes of the script-pubkey. If this Miniscript is used outside of segwit (e.g. in a bare or P2SH descriptor), this quantity should be multiplied by 4 to compute the weight.

In general, it is not recommended to use this function directly, but to instead call the corresponding function on a Descriptor, which will handle the segwit/non-segwit technicalities for you.
