Enum AddrError 

#[non_exhaustive]
pub enum AddrError {
    Syntax {
        at: usize,
    },
    PrefixTooLong {
        max: u8,
    },
    HostBitsSet,
    TooMany {
        max: usize,
    },
    Empty,
}

An error parsing or building an address value.

Examples

use net_io::{AddrError, Cidr};
assert_eq!(Cidr::parse("10.0.0.1/8"), Err(AddrError::HostBitsSet));

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.

Syntax

The text is not an address or block; at is the byte offset where it went wrong.

Fields

at: usize

Byte offset of the problem.

PrefixTooLong

The prefix length is above the family’s maximum.

Fields

max: u8

32 or 128.

HostBitsSet

Bits beyond the prefix are set; use the masked constructor or fix the text.

TooMany

More entries than allowed.

Fields

max: usize

The maximum.

Empty

The text is empty.

Trait Implementations

impl Clone for AddrError

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for AddrError

impl Debug for AddrError

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

Formats the value using the given formatter.

impl Display for AddrError

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

Formats the value using the given formatter.

impl Eq for AddrError

impl Error for AddrError

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<AddrError> for NetError

fn from(e: AddrError) -> NetError

Converts to this type from the input type.

impl PartialEq for AddrError

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

Equality operator ==.

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

Inequality operator !=.
