Struct OpCodeInfo

pub struct OpCodeInfo { /* private fields */ }

Information about opcode, such as name, and stack inputs and outputs.

Implementations

impl OpCodeInfo

pub const fn new(name: &'static str) -> Self

Creates a new opcode info with the given name and default values.

pub const fn name(&self) -> &'static str

Returns the opcode name.

pub const fn io_diff(&self) -> i16

Calculates the difference between the number of input and output stack elements.

pub const fn inputs(&self) -> u8

Returns the number of input stack elements.

pub const fn outputs(&self) -> u8

Returns the number of output stack elements.

pub const fn is_disabled_in_eof(&self) -> bool

Returns whether this opcode is disabled in EOF bytecode.

pub const fn is_terminating(&self) -> bool

Returns whether this opcode terminates execution, e.g. STOP, RETURN, etc.

pub const fn immediate_size(&self) -> u8

Returns the size of the immediate value in bytes.

Trait Implementations

impl Clone for OpCodeInfo

fn clone(&self) -> OpCodeInfo

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for OpCodeInfo

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

Formats the value using the given formatter.

impl Hash for OpCodeInfo

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 Ord for OpCodeInfo

fn cmp(&self, other: &OpCodeInfo) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for OpCodeInfo

fn eq(&self, other: &OpCodeInfo) -> 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.

impl PartialOrd for OpCodeInfo

fn partial_cmp(&self, other: &OpCodeInfo) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
