Struct bitcoin::blockdata::script::Builder

pub struct Builder(_);

An object which can be used to construct a script piece by piece

Methods

impl Builder

pub fn new() -> Builder

Creates a new empty script

pub fn len(&self) -> usize

The length in bytes of the script

pub fn is_empty(&self) -> bool

Whether the script is the empty script

pub fn push_int(self, data: i64) -> Builder

Adds instructions to push an integer onto the stack. Integers are encoded as little-endian signed-magnitude numbers, but there are dedicated opcodes to push some small integers.

pub fn push_scriptint(self, data: i64) -> Builder

Adds instructions to push an integer onto the stack, using the explicit encoding regardless of the availability of dedicated opcodes.

pub fn push_slice(self, data: &[u8]) -> Builder

Adds instructions to push some arbitrary data onto the stack

pub fn push_opcode(self, data: All) -> Builder

Adds a single opcode to the script

pub fn into_script(self) -> Script

Converts the Builder into an unmodifiable Script

Trait Implementations

impl PartialEq<Builder> for Builder

fn eq(&self, other: &Builder) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Builder) -> bool

This method tests for !=.

impl Default for Builder

Adds an individual opcode to the script

fn default() -> Builder

Returns the "default value" for a type.

impl From<Vec<u8>> for Builder

Creates a new script from an existing vector

fn from(v: Vec<u8>) -> Builder

Performs the conversion.

impl Clone for Builder

fn clone(&self) -> Builder

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Eq for Builder

impl Display for Builder

fn fmt(&self, f: &mut Formatter) -> Result<(), Error>

Formats the value using the given formatter.

impl Debug for Builder

fn fmt(&self, f: &mut Formatter) -> Result

Formats the value using the given formatter.

impl Index<Range<usize>> for Builder

type Output = [u8]

The returned type after indexing.

fn index(&self, index: Range<usize>) -> &[u8]

Performs the indexing (container[index]) operation.

impl Index<RangeTo<usize>> for Builder

type Output = [u8]

The returned type after indexing.

fn index(&self, index: RangeTo<usize>) -> &[u8]

Performs the indexing (container[index]) operation.

impl Index<RangeFrom<usize>> for Builder

type Output = [u8]

The returned type after indexing.

fn index(&self, index: RangeFrom<usize>) -> &[u8]

Performs the indexing (container[index]) operation.

impl Index<RangeFull> for Builder

type Output = [u8]

The returned type after indexing.

fn index(&self, _: RangeFull) -> &[u8]

Performs the indexing (container[index]) operation.
