Enum ckb_script::ScriptVersion

pub enum ScriptVersion {
    V0 = 0,
    V1 = 1,
    V2 = 2,
}

The version of CKB Script Verifier.

Variants

V0 = 0

CKB VM 0 with Syscall version 1.

V1 = 1

CKB VM 1 with Syscall version 1 and version 2.

V2 = 2

CKB VM 2 with Syscall version 1, version 2 and version 3.

Implementations

impl ScriptVersion

pub const fn latest() -> Self

Returns the latest version.

pub fn vm_isa(self) -> VmIsa

Returns the ISA set of CKB VM in current script version.

pub fn vm_version(self) -> VmVersion

Returns the version of CKB VM in current script version.

pub fn data_hash_type(self) -> ScriptHashType

Returns the specific data script hash type.

Returns:

• ScriptHashType::Data for version 0;
• ScriptHashType::Data1 for version 1;

pub fn init_core_machine_without_limit(self) -> CoreMachine

Creates a CKB VM core machine without cycles limit.

In fact, there is still a limit of max_cycles which is set to 2^64-1.

pub fn init_core_machine(self, max_cycles: Cycle) -> CoreMachine

Creates a CKB VM core machine.

Trait Implementations

impl Clone for ScriptVersion

fn clone(&self) -> ScriptVersion

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ScriptVersion

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

Formats the value using the given formatter.

impl Ord for ScriptVersion

fn cmp(&self, other: &ScriptVersion) -> 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 + PartialOrd,

Restrict a value to a certain interval.

impl PartialEq for ScriptVersion

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

impl PartialOrd for ScriptVersion

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

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

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

This method tests less than (for self and other) and is used by the < operator.

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

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

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

This method tests greater than (for self and other) and is used by the > operator.

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

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