Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

PushBytes0 = 0

Push an empty array onto the stack.

PushBytes32 = 32

Push the next 32 bytes as an array onto the stack.

Reserved = 80

Synonym for OP_RETURN.

Return = 106

Fail the script immediately.

PushData1 = 76

Read the next byte as N; push the next N bytes as an array onto the stack.

PushData2 = 77

Read the next 2 bytes as N; push the next N bytes as an array onto the stack.

PushData4 = 78

Read the next 4 bytes as N; push the next N bytes as an array onto the stack.

PushNum1 = 81

Push the array 0x01 onto the stack.

Dup = 118

Duplicates the top stack item.

Equal = 135

Pushes 1 if the inputs are exactly equal, 0 otherwise.

EqualVerify = 136

Returns success if the inputs are exactly equal, failure otherwise.

Ripemd160 = 166

Pop the top stack item and push its RIPEMD160 hash.

Sha1 = 167

Pop the top stack item and push its SHA1 hash.

Sha256 = 168

Pop the top stack item and push its SHA256 hash.

Hash160 = 169

Pop the top stack item and push its RIPEMD(SHA256) hash.

Hash256 = 170

Pop the top stack item and push its SHA256(SHA256) hash.

CheckSig = 172

https://en.bitcoin.it/wiki/OP_CHECKSIG pushing 1/0 for success/failure.

CheckSigVerify = 173

https://en.bitcoin.it/wiki/OP_CHECKSIG returning success/failure.

Trait Implementations

impl Clone for OpCode

fn clone(&self) -> OpCode

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for OpCode

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

Formats the value using the given formatter.

impl Display for OpCode

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

Formats the value using the given formatter.

impl From<OpCode> for u8

fn from(value: OpCode) -> u8

Converts to this type from the input type.

impl Hash for OpCode

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for OpCode

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

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

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

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

fn variant_ord(&self) -> u8

impl StrictType for OpCode

const STRICT_LIB_NAME: &'static str = LIB_NAME_BITCOIN
