Struct Submission 

pub struct Submission { /* private fields */ }

A command with its identity fixed, ready to send and to recover.

Built by CantonClient::submission. The three send methods mirror the client’s own; Submission::recover is the one that has no equivalent without a handle, because it needs the change ID the send did not return.

Implementations

impl Submission

pub fn change_id(&self) -> &ChangeId

The command’s complete identity — available before anything is sent.

pub async fn submit(&self) -> Result<()>

Submit without waiting (CommandSubmissionService.Submit).

Errors

Returns an Error if authentication or the RPC fails. A failure here is ambiguous: use Self::recover.

pub async fn submit_and_wait(&self) -> Result<SubmitAndWaitResponse>

Submit and wait for the completion (CommandService.SubmitAndWait).

Errors

Returns an Error if authentication fails or the command is rejected. A transport failure is ambiguous: use Self::recover.

pub async fn submit_and_wait_for_transaction(&self) -> Result<Transaction>

Submit and wait for the committed transaction.

Errors

Returns an Error if authentication fails, the command is rejected, or the response carries no transaction. A transport failure is ambiguous: use Self::recover.

pub async fn recover( &self, begin_offset: i64, timeout: Duration, ) -> Result<Completion>

Read this command’s outcome back from the completion stream, matching on the whole change ID.

begin_offset must be an offset from before the submission — CantonClient::ledger_end taken beforehand is the usual source, since a completion that has already gone past cannot be read again.

Errors

Returns Error::Timeout if no completion arrives within timeout (which, for a command that never reached the participant, is the correct answer), or Error::CommandRejected if the ledger rejected it.
