Enum EncodingError 

#[non_exhaustive]
pub enum EncodingError {
    ValueTooLarge {
        field: &'static str,
        actual: usize,
        max: usize,
    },
    Unencodable {
        field: &'static str,
        reason: String,
    },
}

Errors that can occur when encoding BGP/MRT messages to wire format.

These arise when in-memory data structures contain values that cannot be represented in their wire-format fields (e.g. an AS_PATH segment with more than 255 ASes, or an attribute value exceeding 65535 bytes). All such conditions were previously handled by silently truncating — see issue #313.

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.

ValueTooLarge

A value exceeded the maximum size that fits in its wire-format field.

field names the wire field (e.g. "AS_PATH segment count", "BGP attribute value length"). actual is the byte/element count that overflowed; max is the field’s capacity.

Fields

field: &'static str

actual: usize

max: usize

Unencodable

The value cannot be represented in wire format at all (e.g. ATTR_SET encoding is not implemented, a labeled NLRI has an empty label stack, or a BGP OPEN optional parameter uses the reserved type 255).

Fields

field: &'static str

reason: String

Trait Implementations

impl Clone for EncodingError

fn clone(&self) -> EncodingError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for EncodingError

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

Formats the value using the given formatter.

impl Display for EncodingError

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

Formats the value using the given formatter.

impl Eq for EncodingError

impl Error for EncodingError

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 PartialEq for EncodingError

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

Equality operator ==.

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

Inequality operator !=.
