Enum LintError 

pub enum LintError {
    MissingFrom,
    MissingRecipient,
    BadMessageId(String),
    ControlCharsInHeader(String),
    BadAttachmentFilename(String),
    BodyLineTooLong {
        line_no: usize,
        len: usize,
    },
}

One lint failure category.

Variants

MissingFrom

No From: mailbox set. RFC 5322 §3.6 requires it.

MissingRecipient

Neither To:, Cc:, nor Bcc: set. The message has no recipient.

BadMessageId(String)

Message-ID: value is malformed (missing angle brackets).

ControlCharsInHeader(String)

A header value contains a bare LF or a lone CR (control character that would split the message during parse). The string is the offending header name.

BadAttachmentFilename(String)

An attachment filename contains a CR / LF / NUL (injection vector).

BodyLineTooLong

A body line exceeds 998 octets (RFC 5322 §2.1.1 hard limit) after the CTE was applied.

Fields

line_no: usize

1-based line index in the body block.

len: usize

Length of the offending line in octets.

Trait Implementations

impl Clone for LintError

fn clone(&self) -> LintError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for LintError

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

Formats the value using the given formatter.

impl Display for LintError

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

Formats the value using the given formatter.

impl Error for LintError

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 PartialEq for LintError

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
