Struct SendPolicyError 

pub struct SendPolicyError {
    pub message: String,
    pub retryable: bool,
}

A refusal to send: the per-user policy could not be satisfied.

The policy fails loud rather than fabricating a sender, so a misconfiguration can never cause a send from the wrong — or a shared — mailbox.

Fields

message: String

Human-readable reason the send is refused.

retryable: bool

Whether a retry might succeed. A permanent refusal (false, the default) — no verified identity, an ambiguous subject — will not succeed on retry and should be dead-lettered immediately. A transient refusal (true) — the identity store is momentarily unavailable — is eligible for retry. The send_email host op maps this onto the error status durable dispatch classifies by (permanent → 403, transient → 503).

Implementations

impl SendPolicyError

pub fn new(message: impl Into<String>) -> Self

Build a permanent refusal from a reason (the default: a retry will not help — e.g. no verified sending identity).

pub fn transient(message: impl Into<String>) -> Self

Build a transient refusal from a reason (a retry may succeed — e.g. the identity store is momentarily unavailable).

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting
