Enum ValidationError 

pub enum ValidationError {
    ParseError(Error),
    InvalidRequest {
        reason: &'static str,
        context: Option<String>,
    },
}

Transport-level validation failure.

Variants

ParseError(Error)

-32700 Parse error — the raw frame bytes did not deserialise as JSON. The connection is closed after the response is sent because the stream is in an indeterminate state.

InvalidRequest

-32600 Invalid Request — JSON parsed but violated the JSON-RPC 2.0 request object shape rules.

Fields

reason: &'static str

context: Option<String>

Implementations

impl ValidationError

pub fn is_terminal(&self) -> bool

Whether this error should close the connection immediately after the response frame is written. Parse errors leave the framing state indeterminate; invalid-request errors do not.

pub fn into_jsonrpc_response(self) -> JsonRpcResponse

Translate to the wire-level JSON-RPC response. Both variants carry id: null per spec.

Trait Implementations

impl Debug for ValidationError

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

Formats the value using the given formatter.

impl Display for ValidationError

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

Formats the value using the given formatter.

impl Error for ValidationError

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<Error> for ValidationError

fn from(source: Error) -> Self

Converts to this type from the input type.
