Trait AsError

pub trait AsError {
    // Required methods
    fn kind() -> ErrorKind;
    fn message(&self) -> String;
    fn class(&self) -> String;
    fn details(&self) -> Option<BTreeMap<String, Value>>;
}

Trait representing a structured error with categorized information.

The AsError trait provides a standardized way to define and retrieve detailed error information, including its kind, message, classification, and additional details.

Implementing this trait allows for better error management and debugging by ensuring consistency in error structures.

Required Methods

fn kind() -> ErrorKind

The kind of error.

The error kind represents a categorized type of error, allowing consumers to handle different error types distinctly.

fn message(&self) -> String

The error message.

This message provides a human-readable description of the error.

fn class(&self) -> String

The class or category of the error.

The class helps in further classifying errors, providing an additional layer of categorization beyond ErrorKind.

fn details(&self) -> Option<BTreeMap<String, Value>>

Additional details related to the error.

This method provides an optional key-value mapping of extra data associated with the error, which can be useful for debugging or logging purposes.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
