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)

Sending the request to neovim has failed.

Fields:

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

InternalReceiveError(Canceled, 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)

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)

Neovim encountered an error while executing the reqest.

Fields:

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

WrongValueType(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 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 From<Value> for Box<CallError>

fn from(val: Value) -> Box<CallError>

Converts to this type from the input type.
