Enum LegacyClassificationError 

pub enum LegacyClassificationError {
    Malformed,
    Batch,
    MissingMethod,
    MissingName(Method),
}

Why a legacy request could not be classified from its body.

Variants

Malformed

The body was not JSON.

Batch

A JSON-RPC batch. Several calls in one request cannot be priced as one, and batching was removed from the protocol in 2025-06-18.

MissingMethod

No usable method string.

MissingName(Method)

A name-bearing method arrived without params.name or params.uri.

Trait Implementations

impl Eq for LegacyClassificationError

impl Error for LegacyClassificationError

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 LegacyClassificationError

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

Equality operator ==.

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

Inequality operator !=.
