Struct NeoContractRuntime 

pub struct NeoContractRuntime;

Neo N3 contract management operations.

These are test/example stubs. In deployed contracts, the #[neo_contract] macro generates Wasm imports that map to NeoVM syscalls (System.Contract.Create, System.Contract.Update, System.Contract.Call). The methods here allow compiling and unit-testing contract code off-chain.

• create() returns a zero-filled 20-byte hash (placeholder script hash).
• update() and destroy() succeed immediately with no side effects.
• call() always returns NeoValue::Null.

Implementations

impl NeoContractRuntime

pub fn create( script: &NeoByteString, manifest: &NeoContractManifest, ) -> NeoResult<NeoByteString>

Deploy a new contract. Returns a placeholder 20-byte script hash.

pub fn update( _script_hash: &NeoByteString, script: &NeoByteString, manifest: &NeoContractManifest, ) -> NeoResult<()>

Update an existing contract’s script and manifest.

pub fn destroy(script_hash: &NeoByteString) -> NeoResult<()>

Destroy a contract.

pub fn call( script_hash: &NeoByteString, method: &NeoString, args: &NeoArray<NeoValue>, ) -> NeoResult<NeoValue>

Call another contract’s method. Always returns NeoValue::Null in stubs.
