Enum ckb_script::ScriptVersion

pub enum ScriptVersion {
    V0,
    V1,
}

The version of CKB Script Verifier.

Variants

V0

CKB VM 0 with Syscall version 1.

V1

CKB VM 1 with Syscall version 1 and version 2.

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.
