Enum CallError 

#[non_exhaustive]
pub enum CallError {
    Transport(TransportError),
    Rpc(i32, String, Option<Value>),
}

Result of a CDP call: either a transport-level failure, or a structured JSON-RPC error returned by Chrome. Higher layers (the zendriver crate) map Rpc into the typed ZendriverError::Cdp variant.

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.

Transport(TransportError)

Connection-level failure (see TransportError).

Rpc(i32, String, Option<Value>)

Chrome answered the command with a structured JSON-RPC error. Carries the JSON-RPC code, message, and optional data payload.

Trait Implementations

impl Debug for CallError

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

Formats the value using the given formatter.

impl Display for CallError

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

Formats the value using the given formatter.

impl Error for CallError

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<CallError> for ObserverError

fn from(source: CallError) -> Self

Converts to this type from the input type.

impl From<TransportError> for CallError

fn from(source: TransportError) -> Self

Converts to this type from the input type.
