Enum BridgeError 

pub enum BridgeError {
    Spawn(String),
    Serialisation(String),
    PostMessage(String),
    WorkerError(String),
    WorkerCrashed,
    Terminated,
    ChannelClosed,
    ChannelFull,
    InvalidConfig(String),
}

Errors from the worker bridge.

Variants

Spawn(String)

Worker::new() failed (invalid script URL, CSP, etc.).

Serialisation(String)

Serialisation of a command or event failed.

PostMessage(String)

postMessage rejected by the browser.

WorkerError(String)

Script-level error (wrong URL, CSP, syntax error in worker script). Not automatically recoverable — the script itself is broken.

WorkerCrashed

Worker process crashed (WASM panic, OOM, unreachable trap). A Supervisor should attempt respawn.

Terminated

The worker handle has been terminated.

ChannelClosed

The event channel has been closed (receiver dropped).

ChannelFull

The command channel is full — the worker cannot accept more commands.

InvalidConfig(String)

Builder configuration is invalid.

Implementations

impl BridgeError

pub fn is_crash(&self) -> bool

True if the error indicates the worker process died unexpectedly and respawn may succeed.

pub fn is_permanent(&self) -> bool

True if the error is permanent and respawn will not help.

Trait Implementations

impl Debug for BridgeError

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

Formats the value using the given formatter.

impl Display for BridgeError

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

Formats the value using the given formatter.

impl Error for BridgeError

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>)
