Implementations

impl SpfError

pub fn is_spf_error(&self) -> bool

Returns true if the SpfError is any of those listed SpfError.

pub fn is_invalid_source(&self) -> bool

Returns true if the SpfError indicates and Invalid Source error.

pub fn is_source_length_exceeded(&self) -> bool

Returns true if the SpfError indictes 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 is_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

Returns true if the SpfError indicates an Invalid IP Address

Trait Implementations

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)>

The lower-level source of this error, if any.

fn backtrace(&self) -> Option<&Backtrace>

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

Returns a stack backtrace, if available, of where this error occurred.

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
