Low-level failures reported by the address parsing backend.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

InputContainsRawNewlines

The input contains a raw carriage return or line feed.

#[non_exhaustive]

InputTooLong

The input exceeds MAX_ADDRESS_INPUT_BYTES.

Fields

Non-exhaustive enum variants could have additional fields added in future. Therefore, non-exhaustive enum variants cannot be constructed in external crates and cannot be matched against.

len: usize

Actual input length in bytes.

max: usize

Maximum accepted input length in bytes.

HeaderParse

The backend could not parse the synthetic address header.

MissingAddress

The parsed header did not contain address data.

MissingAddrSpec

A mailbox did not contain an addr-spec.

InvalidAddrSpec

A mailbox contained an invalid addr-spec.

Fields

input: String

Invalid addr-spec text.

source: EmailAddressParseError

Underlying email-address validation error.

GroupMemberMissingAddrSpec

A group member did not contain an addr-spec.

Fields

index: usize

Zero-based index of the invalid member.

InvalidGroupMemberAddrSpec

A group member contained an invalid addr-spec.

Fields

index: usize

Zero-based index of the invalid member.

input: String

Invalid addr-spec text.

source: EmailAddressParseError

Underlying email-address validation error.

GroupMissingName

A parsed group did not contain a name.

Trait Implementations

impl Debug for AddressBackendError

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for AddressBackendError

fn fmt(&self, __formatter: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Error for AddressBackendError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

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

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.
