}

A list of expected and possible errors for SPF records.

Variants

InvalidSource

Source is invalid, SPF struct was not created using from_str()

InvalidVersion

Version is invalid

SourceLengthExceeded

Source string length exceeds 512 Characters

LookupLimitExceeded

Exceeds RFC lookup limit.

HasNotBeenParsed

Source Spf String has not been parsed.

WhiteSpaceSyntaxError

Only one white space is permitted between mechanisms or extra whitespace at the end of the spf string.

InvalidSPF

Invalid SPF

RedirectWithAllMechanism

According to RFC7208, ALL REDIRECT MUST be ignored when found with an
‘ALL’ Mechanism, irrespective of relative location.
See Section 5.1

RedirectNotFinalMechanism

REDIRECT SHOULD be the final item given in an Spf record when present.

ModifierMayOccurOnlyOnce(Kind)

Modifiers may only occur once in any Spf Record

InvalidIPAddr(IpNetworkError)

Network Address is not valid

InvalidMechanism(MechanismError)

SpfError for an invalid Mechanism

DeprecatedPtrDetected

Deprecated ptr detected in Spf record.
According to RFCs ptr is obsolete and should not be used. See Section: 5.5

Implementations

impl SpfError

pub fn is_spf_error(&self) -> bool

pub fn is_invalid_source(&self) -> bool

Returns true if the SpfError indicates and Invalid Source error.

pub fn source_is_invalid(&self) -> bool

Returns true if the SpfError indicates an Invalid Source error.

pub fn version_is_invalid(&self) -> bool

Returns true if the SpfError indicates an invalid version type.

pub fn is_source_length_exceeded(&self) -> bool

Returns true if the SpfError indicates source length exceeds 255 characters.

pub fn source_length_exceeded(&self) -> bool

Returns true if the SpfError indicates source length exceeds 255 characters.

pub fn is_lookup_limit_exceeded(&self) -> bool

Returns true if the SpfError indicates SPF contains more than 10 DNS lookups.

pub fn lookup_limit_exceeded(&self) -> bool

Returns true if the SpfError indicates SPF contains more than 10 DNS lookups.

pub fn is_has_not_been_parsed(&self) -> bool

Returns true if the SpfError indicates source of Spf has not been parsed.

pub fn has_not_been_parsed(&self) -> bool

Returns true if the SpfError indicates source of Spf has not been parsed.

pub fn is_invalid_spf(&self) -> bool

Returns true if the SpfError indicates this is an invalid Spf Record.

pub fn is_redirect_with_all_mechanism(&self) -> bool

Returns true if the SpfError indicates the presents of All Mechanism

pub fn is_invalid_ip_addr(&self) -> bool

Trait Implementations

impl Clone for SpfError

fn clone(&self) -> SpfError

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for SpfError

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

Formats the value using the given formatter.

impl Display for SpfError

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

Formats the value using the given formatter.

impl Error for SpfError

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<IpNetworkError> for SpfError

fn from(err: IpNetworkError) -> Self

Converts to this type from the input type.

impl From<MechanismError> for SpfError

fn from(err: MechanismError) -> Self

Converts to this type from the input type.

impl PartialEq for SpfError

fn eq(&self, other: &SpfError) -> 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.
