Enum TopologyError 

pub enum TopologyError {
    Truncated,
    BodyLengthMismatch {
        declared: u32,
        available: usize,
    },
    InvalidUtf8,
    StringTooLong {
        declared: u32,
        remaining: usize,
    },
}

Decode-side errors. Distinct from “unknown version tag”, which is reported as Ok(None) on decode_topology so the consumer can fall back to URI-only routing without branching on an error variant.

Trait Implementations

impl Clone for TopologyError

fn clone(&self) -> TopologyError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TopologyError

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

Formats the value using the given formatter.

impl Display for TopologyError

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

Formats the value using the given formatter.

impl Error for TopologyError

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 TopologyError

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