Enum nvim_rs::error::CallError

pub enum CallError {
    SendError(EncodeError, String),
    InternalReceiveError(Canceled, String),
    DecodeError(Arc<DecodeError>, String),
    NeovimError(Option<i64>, String),
    WrongValueType(Value),
}

A call to neovim failed

The API functions return this, as they are just proxies for call.

Variants

SendError(EncodeError, String)

Tuple Fields

0: EncodeError

1: String

Sending the request to neovim has failed.

Fields:

0. The underlying error
1. The name of the called method

InternalReceiveError(Canceled, String)

Tuple Fields

0: Canceled

1: String

The internal channel to send the response to the right task was closed. This really should not happen, unless someone manages to kill individual tasks.

Fields:

0. The underlying error
1. The name of the called method

DecodeError(Arc<DecodeError>, String)

Tuple Fields

0: Arc<DecodeError>

1: String

Decoding neovim’s response failed.

Fields:

0. The underlying error
1. The name of the called method

Note: DecodeError can’t be Clone, so we Arc-wrap it

NeovimError(Option<i64>, String)

Tuple Fields

0: Option<i64>

1: String

Neovim encountered an error while executing the reqest.

Fields:

0. Neovim’s error type (see :h api)
1. Neovim’s error message

WrongValueType(Value)

Tuple Fields

0: Value

The response from neovim contained a Value of the wrong type

Implementations

impl CallError

pub fn is_channel_closed(&self) -> bool

Determine if the error originated from a closed channel. This is generally used to close a plugin from neovim’s side, and so most of the time should not be treated as a real error, but a signal to finish the program.

Trait Implementations

impl Debug for CallError

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

Formats the value using the given formatter.

impl Display for CallError

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

Formats the value using the given formatter.

impl Error for CallError

fn source(&self) -> Option<&(dyn Error + 'static)>

The lower-level source of this error, if any.

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

🔬 This is a nightly-only experimental API. (backtrace)

Returns a stack backtrace, if available, of where this error occurred.

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
