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.

EvalTimeout

A JavaScript eval timed out waiting for a response from the webview.

Fields

timeout_secs: u64

How many seconds elapsed before the timeout.

EvalFailed

A JavaScript eval returned an error from the webview.

Fields

message: String

The error message from the webview.

EvalConcurrencyExceeded

Too many concurrent eval requests are pending.

Fields

limit: usize

The maximum number of concurrent eval requests.

BridgeError

The webview bridge returned an error.

Fields

message: String

The error message from the bridge.

ScreenshotFailed

Screenshot capture failed.

Fields

message: String

The error message from the screenshot subsystem.

AuthenticationFailed

Bearer-token authentication failed.

Fields

message: String

The error message describing the auth failure.

RateLimitExceeded

The rate limiter rejected the request.

ToolDisabled

The requested tool is disabled by the privacy configuration.

Fields

tool_name: String

Name of the disabled tool.

CommandBlocked

The requested command is blocked by the privacy configuration.

Fields

command: String

Name of the blocked command.

WindowNotFound

No window with the given label was found.

Fields

label: String

The window label that was not found.

ServerStartFailed

The MCP server failed to start (e.g., all ports in use).

Fields

message: String

The error message from the server startup.

PortInUse

The configured port is already bound by another process.

Fields

port: u16

The port that is already in use.

Serialization(Error)

JSON serialization or deserialization failed.

Io(Error)

Trait Implementations

impl Debug for PluginError

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

Formats the value using the given formatter.

impl Display for PluginError

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

Formats the value using the given formatter.

impl Error for PluginError

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.
