Struct ScriptChunk 

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

A representation of a chunk of a script, which includes an opcode. For push operations, the associated data to push onto the stack is also included.

Fields

op: u8

The opcode value

data: Option<Vec<u8>>

Data for push operations (None for non-push ops)

Implementations

impl ScriptChunk

pub fn new_opcode(op: u8) -> Self

Creates a new opcode-only chunk (no data).

pub fn new_push(data: Vec<u8>) -> Self

Creates a new data push chunk.

The appropriate opcode is determined based on the data length:

• 0 bytes: OP_0
• 1-75 bytes: direct push (opcode = length)
• 76-255 bytes: OP_PUSHDATA1
• 256-65535 bytes: OP_PUSHDATA2
• Larger: OP_PUSHDATA4

pub fn new(op: u8, data: Option<Vec<u8>>) -> Self

Creates a chunk from an opcode and optional data.

pub fn is_push_data(&self) -> bool

Returns true if this chunk is a data push operation.

pub fn to_asm(&self) -> String

Converts this chunk to its ASM string representation.

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 Default for ScriptChunk

fn default() -> Self

Returns the “default value” for a type.

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.
