Enum AspectError 

pub enum AspectError {
    ExecutionError {
        message: String,
        source: Option<Box<dyn Error + Send + Sync>>,
    },
    WeavingError {
        message: String,
    },
    Custom(Box<dyn Error + Send + Sync>),
}

Errors that can occur during aspect execution.

This type wraps errors that occur during the execution of advised functions or within aspect logic itself.

Variants

ExecutionError

An error occurred during function execution

Fields

message: String

The underlying error message

source: Option<Box<dyn Error + Send + Sync>>

Optional source error

WeavingError

An error occurred during aspect weaving

Fields

message: String

Description of the weaving error

Custom(Box<dyn Error + Send + Sync>)

A custom error defined by user code

Implementations

impl AspectError

pub fn execution(message: impl Into<String>) -> Self

Creates a new execution error.

Example

use aspect_core::error::AspectError;

let err = AspectError::execution("Database connection failed");

pub fn execution_with_source( message: impl Into<String>, source: impl Error + Send + Sync + 'static, ) -> Self

Creates a new execution error with a source.

Example

use aspect_core::error::AspectError;
use std::io;

let io_err = io::Error::new(io::ErrorKind::NotFound, "file not found");
let err = AspectError::execution_with_source("Failed to read file", io_err);

pub fn weaving(message: impl Into<String>) -> Self

Creates a new weaving error.

Example

use aspect_core::error::AspectError;

let err = AspectError::weaving("Invalid pointcut expression");

pub fn custom(error: impl Error + Send + Sync + 'static) -> Self

Creates a custom error from any error type.

Example

use aspect_core::error::AspectError;
use std::io;

let io_err = io::Error::new(io::ErrorKind::Other, "custom error");
let err = AspectError::custom(io_err);

Trait Implementations

impl Debug for AspectError

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

Formats the value using the given formatter.

impl Display for AspectError

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

Formats the value using the given formatter.

impl Error for AspectError

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<&str> for AspectError

fn from(s: &str) -> Self

Converts to this type from the input type.

impl From<Box<dyn Error + Send + Sync>> for AspectError

fn from(err: Box<dyn Error + Send + Sync>) -> Self

Converts to this type from the input type.

impl From<String> for AspectError

fn from(s: String) -> Self

Converts to this type from the input type.
