Enum Error 

pub enum Error {
    Parse(String),
    BadSpec(String),
    EngineMismatch {
        expected: String,
        linked: String,
    },
    Backtest(String),
    Data(String),
}

Errors returned by wickra-proof-core operations. Every fallible boundary (parsing, engine invocation, canonicalization) maps into one of these; no operation panics on caller-supplied input.

Variants

Parse(String)

A JSON or TOML value failed to parse.

BadSpec(String)

The embedded strategy JSON is not a valid StrategySpec.

EngineMismatch

The pinned engine_version differs from the linked backtest engine.

Fields

expected: String

The version pinned in the ProofSpec.

linked: String

The version of the linked wickra-backtest engine.

Backtest(String)

The backtest engine returned an error.

Data(String)

The data map lacked the candles required by the strategy.

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, __formatter: &mut Formatter<'_>) -> Result

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<Error> for Error

fn from(e: Error) -> Self

Converts to this type from the input type.
