Enum PythonCallError 

pub enum PythonCallError {
    InvalidMethodIndex {
        index: usize,
        count: usize,
    },
    WireModeMismatch {
        method: &'static str,
        declared: bool,
        attempted: bool,
    },
    InputDecode(String),
    OutputEncode(String),
    Plugin(PluginError),
}

Errors a typed call can produce on the Python side.

Variants

InvalidMethodIndex

method_index was past the end of the interface descriptor’s methods.

Fields

index: usize

count: usize

WireModeMismatch

Tried to call a typed method through the raw path, or vice versa.

Fields

method: &'static str

declared: bool

attempted: bool

InputDecode(String)

The host-supplied input bytes (typed path) couldn’t be decoded.

OutputEncode(String)

The Python return value couldn’t be encoded back for the host.

Plugin(PluginError)

A Python exception was raised by the plugin.

Trait Implementations

impl Debug for PythonCallError

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

Formats the value using the given formatter.

impl Display for PythonCallError

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

Formats the value using the given formatter.

impl Error for PythonCallError

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.
