Struct ContractType 

#[repr(transparent)]
pub struct ContractType(pub i32);

The execution environment for a contract.

Discriminant 0 is retired. It selected an earlier contract runtime, which was removed once RV32 became the only deployable execution environment. Do not reuse the value: old encodings that carry it must fail to parse rather than silently decode as a live contract type.

Tuple Fields

0: i32

Implementations

impl ContractType

pub const kNative: ContractType

Precompiled native contract implemented natively by the node.

Used for system contracts like the native token. Cheaper to invoke than a deployed RV32 contract, but users cannot deploy new ones.

pub const kMockTest: ContractType

Mock contract for local testing.

Never deployed on-chain; exists only in the test harness.

pub const kRv32: ContractType

RiscV contract executed in the RV32 VM.

This is the standard contract type for user-deployed contracts.

fn json_schema(generator: &mut SchemaGenerator) -> Schema

Generates a JSON Schema for this type.

fn inline_schema() -> bool

impl Ord for ContractType

fn cmp(&self, other: &ContractType) -> 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.
