Struct Builder 

pub struct Builder<T>(/* private fields */);

An Object which can be used to construct a script piece by piece.

Panics

Builder is backed by ScriptBuf and inherits its panic behavior. This means that attempting to construct scripts larger than isize::MAX bytes will panic.

Implementations

impl<T> Builder<T>

pub const fn new() -> Self

Constructs a new empty script.

pub fn push_slice<D: AsRef<PushBytes>>(self, data: D) -> Self

Adds instructions to push some arbitrary data onto the stack.

If the data can be exactly produced by a numeric opcode, that opcode will be used, since its behavior is equivalent but will not violate minimality rules. To avoid this, use Builder::push_slice_non_minimal which will always use a push opcode.

However, this method does not enforce any numeric minimality rules. If your pushes should be interpreted as numbers, ensure your input does not have any leading zeros. In particular, the number 0 should be encoded as an empty string rather than as a single 0 byte.

pub fn push_slice_non_minimal<D: AsRef<PushBytes>>(self, data: D) -> Self

Adds instructions to push some arbitrary data onto the stack without minimality.

Standardness rules require push minimality according to CheckMinimalPush of core.

pub fn push_opcode(self, data: Opcode) -> Self

Adds a single opcode to the script.

pub fn into_script(self) -> ScriptBuf<T>

Converts the Builder into ScriptBuf.

pub fn as_script(&self) -> &Script<T>

Returns the internal script
