The details of a failed send.

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.

status: Option<u16>

The HTTP status, or None when no answer was received.

code: String

The API error code (invalid_key, quota_exceeded, validation_failed, …), or network_error / timeout.

message: String

A human-readable explanation (English).

fields: Vec<FieldError>

Every invalid field, for Error::Validation.

local: bool

true when the SDK rejected the message before sending anything.

request_id: Option<String>

The server’s request id (req_…), when it answered.

idempotency_key: Option<String>

The Idempotency-Key that was used. Retry later with the same key to stay duplicate-free.

attempts: u32

The number of HTTP attempts made (0 when rejected locally).

retry_after: Option<Duration>

The server’s Retry-After, when present.
