Implementations§
Source§impl System
impl System
Sourcepub fn remark(&self, remark: Vec<u8>) -> SubmittableTransaction
pub fn remark(&self, remark: Vec<u8>) -> SubmittableTransaction
Emits a remark event containing arbitrary bytes.
§Arguments
remark- Payload recorded on chain.
§Returns
Returns a SubmittableTransaction that emits the remark.
§Errors
Does not perform network calls; transaction construction never fails.
Sourcepub fn set_code(&self, code: Vec<u8>) -> SubmittableTransaction
pub fn set_code(&self, code: Vec<u8>) -> SubmittableTransaction
Replaces the runtime code with a new version.
§Arguments
code- WASM runtime bytecode.
§Returns
Returns a SubmittableTransaction that schedules the code upgrade.
§Errors
Does not perform network calls; transaction construction never fails.
Sourcepub fn set_code_without_checks(&self, code: Vec<u8>) -> SubmittableTransaction
pub fn set_code_without_checks(&self, code: Vec<u8>) -> SubmittableTransaction
Replaces the runtime code without performing standard checks.
§Arguments
code- WASM runtime bytecode.
§Returns
Returns a SubmittableTransaction that forces the code upgrade.
§Errors
Does not perform network calls; transaction construction never fails.
Sourcepub fn remark_with_event(&self, remark: Vec<u8>) -> SubmittableTransaction
pub fn remark_with_event(&self, remark: Vec<u8>) -> SubmittableTransaction
Emits a remark while guaranteeing an event is produced.
§Arguments
remark- Payload recorded on chain.
§Returns
Returns a SubmittableTransaction that emits the remark alongside an event.
§Errors
Does not perform network calls; transaction construction never fails.
