Struct Error

pub struct Error { /* private fields */ }

An error that can occur while using Cot.

Implementations

impl Error

pub fn custom<E>(error: E) -> Self

where E: Into<Box<dyn Error + Send + Sync + 'static>>,

Create a new error with a custom error message or error type.

Examples

use cot::Error;

let error = Error::custom("An error occurred");
let error = Error::custom(std::io::Error::new(
    std::io::ErrorKind::Other,
    "An error occurred",
));

pub fn admin<E>(error: E) -> Self

where E: Into<Box<dyn Error + Send + Sync + 'static>>,

Create a new admin panel error with a custom error message or error type.

Examples

use cot::Error;

let error = Error::admin("An error occurred");
let error = Error::admin(std::io::Error::new(
    std::io::ErrorKind::Other,
    "An error occurred",
));

pub fn not_found() -> Self

Create a new “404 Not Found” error without a message.

Examples

use cot::Error;

let error = Error::not_found();

pub fn not_found_message(message: String) -> Self

Create a new “404 Not Found” error with a message.

Note that the message is only displayed when Cot’s debug mode is enabled. It will not be exposed to the user in production.

Examples

use cot::Error;

let id = 123;
let error = Error::not_found_message(format!("User with id={id} not found"));

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

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
