Enum CdpError 

#[non_exhaustive]
pub enum CdpError {
    WebSocket(String),
    Remote {
        code: i64,
        message: String,
    },
    Decode(String),
    Timeout {
        elapsed: Duration,
        what: &'static str,
    },
    Closed,
}

Errors a CdpClient can surface.

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.

WebSocket(String)

WebSocket transport failure (handshake, TLS, abrupt close, …).

Remote

CDP responded with {"error": {"code": …, "message": …}} for our command. Carries the protocol-level details.

Fields

code: i64

Numeric CDP error code (e.g. -32601 for method-not-found).

message: String

Human-readable message from the remote.

Decode(String)

Response decoded as JSON but didn’t match the typed R we asked for. Wraps the underlying serde error.

Timeout

execute (or wait_for_event) blocked past its deadline.

Fields

elapsed: Duration

Duration the call waited before giving up.

what: &'static str

Friendly label for the kind of wait (e.g. "Page.navigate").

Closed

The client was used after CdpClient::close (or the read loop exited because the peer closed the connection).

Trait Implementations

impl Debug for CdpError

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

Formats the value using the given formatter.

impl Display for CdpError

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

Formats the value using the given formatter.

impl Error for CdpError

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.
