Struct bitcoin::blockdata::script::Builder[−][src]

pub struct Builder(_, _);

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

Implementations

`impl Builder`[src]

`pub fn new() -> Self`[src]

Creates a new empty script

`pub fn len(&self) -> usize`[src]

The length in bytes of the script

`pub fn is_empty(&self) -> bool`[src]

Whether the script is the empty script

`pub fn push_int(self, data: i64) -> Builder`[src]

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`[src]

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`[src]

Adds instructions to push some arbitrary data onto the stack

`pub fn push_key(self, key: &PublicKey) -> Builder`[src]

Pushes a public key

`pub fn push_opcode(self, data: All) -> Builder`[src]

Adds a single opcode to the script

`pub fn push_verify(self) -> Builder`[src]

Adds an OP_VERIFY to the script, unless the most-recently-added opcode has an alternate VERIFY form, in which case that opcode is replaced. e.g. OP_CHECKSIG will become OP_CHECKSIGVERIFY.

`pub fn into_script(self) -> Script`[src]

Converts the Builder into an unmodifiable Script

Trait Implementations

`impl Clone for Builder`[src]

`fn clone(&self) -> Builder`[src]

`pub fn clone_from(&mut self, source: &Self)`1.0.0 [src]

`impl Debug for Builder`[src]

`fn fmt(&self, f: &mut Formatter<'_>) -> Result`[src]

`impl Default for Builder`[src]

Adds an individual opcode to the script

`fn default() -> Builder`[src]

`impl Display for Builder`[src]

`fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>`[src]

`impl From<Vec<u8, Global>> for Builder`[src]

Creates a new script from an existing vector
