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.

#[non_exhaustive]

HeaderContainsRawNewline

A header value contains a raw carriage return or line feed.

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.

name: String

Invalid header name.

#[non_exhaustive]

HeaderContainsControlCharacter

A header value contains a forbidden control character.

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.

name: String

Invalid header name.

#[non_exhaustive]

HeaderContainsNonAscii

A header remains non-ASCII after applicable encoding.

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.

name: String

Invalid header name.

#[non_exhaustive]

InvalidHeaderName

A header name violates RFC 5322 field-name syntax.

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.

name: String

Invalid header name.

#[non_exhaustive]

HeaderLineTooLong

A header cannot be folded below the RFC 5322 hard line limit.

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.

name: String

Overlong header name.

DateFormat

The message date could not be formatted as RFC 2822.

EmptyMimeBoundary

A MIME boundary is empty.

InvalidMimeBoundary

A MIME boundary contains bytes forbidden by the supported grammar.

MismatchedMimeBoundary

The content-type boundary parameter differs from the part boundary.

EmptyMultipartParts

A multipart node contains no child parts.

MimeNestingTooDeep

A MIME tree exceeds MAX_MULTIPART_DEPTH.

InvalidMultipartContentType

A multipart node’s content type is not multipart/*.

UnsupportedAttachmentBody

An unresolved attachment reference cannot be rendered.

InvalidContentId

An attachment content id is not a valid message-id value.

UnsupportedBody

The message contains a body variant unsupported by this renderer.

MessageValidation(MessageValidationError)

The message failed baseline outbound validation.

Trait Implementations

impl Clone for MessageRenderError

fn clone(&self) -> MessageRenderError

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for MessageRenderError

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

Formats the value using the given formatter.

impl Display for MessageRenderError

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

impl Eq for MessageRenderError

impl Error for MessageRenderError

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<MessageValidationError> for MessageRenderError

fn from(source: MessageValidationError) -> Self

Converts to this type from the input type.

impl PartialEq for MessageRenderError

fn eq(&self, other: &MessageRenderError) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
