Struct ScriptChunk 

pub struct ScriptChunk {
    pub op: Op,
    pub op_byte: u8,
    pub data: Option<Vec<u8>>,
}

A single parsed element of a script.

Fields

op: Op

The opcode. For direct pushes (0x01..=0x4b) this is the raw byte cast via Op::from, which gives OpInvalidOpcode. The parser stores the raw byte value as op_byte instead.

op_byte: u8

For push operations this carries the raw opcode byte (which may be a direct-push length 0x01..=0x4b that has no named Op variant).

data: Option<Vec<u8>>

The pushed data, if any.

Implementations

impl ScriptChunk

pub fn new_opcode(op: Op) -> Self

Create a new chunk with just an opcode (no data).

pub fn new_raw(op_byte: u8, data: Option<Vec<u8>>) -> Self

Create a new chunk from a raw opcode byte and optional data.

pub fn len(&self) -> usize

Serialized byte length of this chunk.

pub fn is_empty(&self) -> bool

Whether the chunk has a non-zero serialized length (always true).

pub fn to_asm(&self) -> String

ASM string representation.

Data pushes render as lowercase hex. Opcodes render as their name.

pub fn serialize(&self) -> Vec<u8>

Serialize this chunk to binary bytes.

Trait Implementations

impl Clone for ScriptChunk

fn clone(&self) -> ScriptChunk

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ScriptChunk

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

Formats the value using the given formatter.

impl PartialEq for ScriptChunk

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
