Enum MechanismError 

pub enum MechanismError {
    InvalidMechanismFormat(String),
    InvalidMechanismFormatByKind(String, String),
    NotIP4Network(String),
    NotIP6Network(String),
    InvalidIPNetwork(IpNetworkError),
    NotIpNetworkMechanism,
    NotStringMechanism,
    InvalidDomainHost(String),
}

Error message when unable to construct a new Mechanism.

Variants

InvalidMechanismFormat(String)

Indicates that the provided string is not correctly formed.

InvalidMechanismFormatByKind(String, String)

. Indicates that the provided string does not match the required format for the Mechanism Kind.

NotIP4Network(String)

Indicates that the provided string could not be parsed into an IpNetwork::IP4 though it is a valid IpNetwork.

NotIP6Network(String)

Indicates that the provided string could not be parsed into an IpNetwork::IP6 though it is a valid IpNetwork.

InvalidIPNetwork(IpNetworkError)

Indicates that the provided string does not contain any valid IpNetwork.

NotIpNetworkMechanism

Attempted to access a Mechanism as a Mechanism<IpNetwork> but is Mechanism<String>

NotStringMechanism

Attempted to access a Mechanism as a Mechanism<String> but is Mechanism<IpNetwork>

InvalidDomainHost(String)

Indicates that the host record is not valid. Does not conform to RFC1123

Implementations

impl MechanismError

pub fn is_invalid_format(&self) -> bool

Returns true if it is not a valid Mechanism format.

pub fn is_not_ip4_network(&self) -> bool

Return true if it is a valid IpNetwork but not an IP4 network.

Example:

“ip4:2001:4860:4000::/36” would give this error. Expected an IP4 network but given an IP6 network.

pub fn is_not_ip6_network(&self) -> bool

Return true if it is a valid IpNetwork but not an IP6 network.

Example:

“ip4:203.32.160.0/24” would give this error. Expected an IP6 network but given an IP4 network.

pub fn is_invalid_ip(&self) -> bool

Return true if the string can not be parsed to an IpNetwork

Example:

“ip4:203.32.160.0/33” would give this error. This applies to IP6 networks.

Trait Implementations

impl Clone for MechanismError

fn clone(&self) -> MechanismError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MechanismError

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

Formats the value using the given formatter.

impl Display for MechanismError

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

Formats the value using the given formatter.

impl Error for MechanismError

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 MechanismError

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 MechanismError

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