pub enum CommonError {
    InvalidInput(String),
    Config(String),
    Io(Error),

Available on crate feature error only.

Common error type for ecosystem projects.

This enum covers the most common error cases encountered across projects. For project-specific errors, consider wrapping this or creating derived types.

Variants

InvalidInput(String)

Invalid input provided to a function.

Config(String)

Configuration error.

Io(Error)

IO operation failed.

Parse(String)

Parse error for various formats.

NotFound(String)

Resource not found.

PermissionDenied(String)

Operation not permitted.

Timeout(String)

Operation timed out.

External(String)

External service error.

Custom(String)

Generic error with custom message.

Implementations

impl CommonError

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

Create a new invalid input error.

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

Create a new configuration error.

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

Create a new parse error.

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

Create a new not found error.

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

Create a new custom error.

pub const fn is_input_error(&self) -> bool

Check if this is an input validation error.

pub const fn is_recoverable(&self) -> bool

Check if this is a recoverable error.

Trait Implementations

impl Debug for CommonError

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

Formats the value using the given formatter.

impl Display for CommonError

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

Formats the value using the given formatter.

impl Error for CommonError

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 CommonError

fn from(source: Error) -> Self

Converts to this type from the input type.
