Enum GroupParseError 

#[non_exhaustive]
pub enum GroupParseError {
    ExpectedSingleGroup {
        found: usize,
    },
    UnexpectedAddressKind,
    Backend {
        source: AddressBackendError,
    },
}

Errors returned when parsing a Group.

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.

ExpectedSingleGroup

The input contained zero or multiple address items.

Fields

found: usize

Number of address items found.

UnexpectedAddressKind

The single address item was a mailbox rather than a group.

Backend

The address parsing backend failed.

Fields

source: AddressBackendError

The underlying backend error.

Trait Implementations

impl Debug for GroupParseError

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

Formats the value using the given formatter.

impl Display for GroupParseError

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

Formats the value using the given formatter.

impl Error for GroupParseError

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.

impl From<GroupParseError> for ParseError

fn from(source: GroupParseError) -> Self

Converts to this type from the input type.
