Struct RestateSendOptions 

#[non_exhaustive]
pub struct RestateSendOptions {
    pub invocation_mode: Option<InvocationMode>,
    pub delay: Option<Duration>,
}

Restate-specific options for a single send attempt.

This is the one typed value inserted into email_transport::SendOptions::transport_options for Restate. It travels under the provider key "restate" and overrides the defaults configured on the caller-side RestateTransport for one send.

The slot is forwarded to the worker in the queued payload like every other provider slice. Workers ignore it unless their transport registry itself contains a Restate-backed transport, in which case the same mode and delay apply to the second hop as well.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

invocation_mode: Option<InvocationMode>

Override the transport’s configured InvocationMode for this send.

delay: Option<Duration>

Delay before Restate starts the worker invocation.

Sent as the ingress delay query parameter, encoded as whole milliseconds rounded up. Only valid with InvocationMode::Queued; combining it with InvocationMode::Sent fails the send with ErrorKind::Validation before any request is made.

This is provider scheduling behavior, not a delivery constraint: a transport that does not recognize the restate slot delivers now rather than later.
