Implementations

impl CommandError

pub fn handle(&self)

Prints the formatted error message to standard error.

This uses the type’s Display implementation to produce a user-facing message.

Examples

use yesser_todo_errors::command_error::CommandError;

let err = CommandError::NoTasksSpecified;
err.handle(); // prints "No tasks specified!" to stderr

Trait Implementations

impl Debug for CommandError

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

Formats the value using the given formatter.

impl Display for CommandError

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

Format the error as a concise, user-facing message.

Examples

use yesser_todo_errors::command_error::CommandError;

assert_eq!(
    format!("{}", CommandError::TaskNotFound { name: "foo".into() }),
    "Task foo not found!"
);

assert_eq!(
    format!("{}", CommandError::NoTasksSpecified),
    "No tasks specified!"
);

impl Error for CommandError

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.
