Unified error type for script compilation and execution.

This enum covers all errors that can occur when building or running an Navi instance. It is serialisable and can be sent over the wire.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Compile(CompileErrors)

One or more compilation errors.

Exception(RuntimeError)

A runtime exception.

MissingScriptType

The script is missing an indicator/strategy/library declaration.

InputValueNotFound

An input.*() call referenced a non-existent input index.

Fields

id: usize

The input index that was not found.

SetInputValue

Failed to serialize an input value override.

Fields

id: usize

The input index being set.

error: String

The serialization error message.

UnsupportedTimeFrame

The requested time frame is not supported.

Fields

time_frame: TimeFrame

The unsupported time frame.

SessionNotAllowed

The trade session is not allowed for this symbol.

Fields

session: TradeSession

The disallowed session.

InvalidSymbol

The symbol string has an invalid format (expected PREFIX:TICKER).

UnknownMarket

The symbol prefix does not map to a known market.

LibraryScriptNotExecutable

Library scripts cannot be executed directly.

DataProvider

The data provider returned an error.

Fields

message: String

The underlying error message.

ConfirmedBarUpdate

Attempted to update a bar that has already been confirmed.

JitCompilation

JIT compilation failed.

Fields

message: String

The underlying error message.

Trait Implementations

impl Clone for Error

fn clone(&self) -> Error

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Error

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Error

fn deserialize<__D>( __deserializer: __D, ) -> Result<Error, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

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 From<CompileErrors> for Error

fn from(source: CompileErrors) -> Error

Converts to this type from the input type.

impl From<RuntimeError> for Error

fn from(source: RuntimeError) -> Error

Converts to this type from the input type.

impl Serialize for Error

fn serialize<__S>( &self, __serializer: __S, ) -> Result<<__S as Serializer>::Ok, <__S as Serializer>::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
