Variants

InvalidPath

The plugin path passed to Sandbox::load_module was not valid UTF-8.

Fields

source: Utf8Error

backtrace: Backtrace

Spawn

Spawning the plugin subprocess failed (binary missing, no execute permission, etc.).

Fields

source: Error

backtrace: Backtrace

WriteRequest

Writing a request frame to the plugin’s stdin failed.

Fields

source: Error

backtrace: Backtrace

ReadResponse

Reading a response frame from the plugin’s stdout failed (EOF, truncated length header, etc.).

Fields

source: Error

backtrace: Backtrace

Protocol

A response frame was malformed JSON, or did not match the expected protocol shape.

Fields

reason: String

backtrace: Backtrace

PluginError

The plugin reported an error for the call.

Fields

method: String

message: String

backtrace: Backtrace

ArgumentType

An argument value could not be marshaled to/from the protocol (e.g. Value::Bytes on a path that only carries scalars).

Fields

function: String

backtrace: Backtrace

FunctionNotFound

The requested function is not exported by the plugin.

Fields

function: String

backtrace: Backtrace

Implementations

impl Error

pub fn code(&self) -> u32

Numeric error code for the process sandbox ABI. Disjoint from core (1..), TC (0x1000..), and the WASM sandbox (0x2000..); process sandbox codes begin at 0x2100.

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

where Self: Debug + Display,

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 ErrorCompat for Error

fn backtrace(&self) -> Option<&Backtrace>

Returns a Backtrace that may be printed.

fn iter_chain(&self) -> ChainCompat<'_, '_>

where Self: AsErrorSource,

Returns an iterator for traversing the chain of errors, starting with the current error and continuing with recursive calls to Error::source.
