Enum MaxLenError 

#[non_exhaustive]
pub enum MaxLenError {
    Overflow,
    Underflow,
}

A max-len prefix was constructed from illegal components.

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.

Overflow

The max-len is larger than allowed for the address family.

Underflow

The max-len is smaller than the prefix length.

Implementations

impl MaxLenError

pub fn static_description(self) -> &'static str

Returns a static error message.

Trait Implementations

impl Clone for MaxLenError

fn clone(&self) -> MaxLenError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MaxLenError

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

Formats the value using the given formatter.

impl Display for MaxLenError

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

Formats the value using the given formatter.

impl Error for MaxLenError

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<MaxLenError> for &'static str

fn from(err: MaxLenError) -> Self

Converts to this type from the input type.

impl PartialEq for MaxLenError

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