Enum Error 

pub enum Error {
    Exchange(String),
    Brain(String),
    Risk(String),
    Config(String),
    Serde(Error),
    Storage(String),
    Internal(String),
}

Framework-level errors.

Exchange adapters, brain implementations, and risk checks wrap their domain-specific errors in one of these variants.

Variants

Exchange(String)

The exchange rejected the request, or the connection to it failed.

Brain(String)

The brain returned an error while processing a market event.

Risk(String)

A risk check blocked an action.

Config(String)

Configuration is invalid or incomplete.

Serde(Error)

Serialization or deserialization failed.

Storage(String)

A state-store persistence failure (backend I/O, corrupt snapshot).

Internal(String)

An otherwise-uncategorised framework error.

Implementations

Convenience constructor for Brain variant.

pub fn risk(msg: impl Into<String>) -> Self

Convenience constructor for Risk variant.

pub fn config(msg: impl Into<String>) -> Self

Convenience constructor for Config variant.

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(source: Error) -> Self

Converts to this type from the input type.
