Enum codeforces_api::Error

pub enum Error {
    Http(Error),
    Parse(Error),
    CodeforcesApi(String),
    Testcases(&'static str),
}

Error type for requests sent through this crate.

When sending a request is unsuccessful, a variant of the Error type will be returned.

Variants

Http(Error)

Http errors are a wrapper for network errors returned internally by reqwest.

This could be returned if, for example, the device is not connected to the internet. Further documentation can be found with the reqwest::Error type.

Parse(Error)

Parse errors are a wrapper for parsing errors returned internally by reqwest.

This could be returned if, for example, the Codeforces API returns malformed JSON. Further documentation can be found with the reqwest::Error type.

CodeforcesApi(String)

CodeforcesApi errors are returned when the Codeforces API returns a status: FAILED response, the comment field of the response is returned as a String

Testcases(&'static str)

Testcases errors are returned only when grabbing testcases which uses webscraping internally since the Codeforces API does not provide it.

For now, a simple message (&'static str) is returned, outlining the error. However, in future, this could/should be moved into its own enum.

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

Display the error with a short description of the error type as a prefix.

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

Formats the value using the given formatter.

impl Error for Error

Standard error impl for custom error type.

fn source(&self) -> Option<&(dyn Error + 'static)>

The lower-level source of this error, if any.

pub fn backtrace(&self) -> Option<&Backtrace>

🔬 This is a nightly-only experimental API. (backtrace)

Returns a stack backtrace, if available, of where this error occurred.

pub fn description(&self) -> &str

👎 Deprecated since 1.42.0:

use the Display impl or to_string()

pub fn cause(&self) -> Option<&dyn Error>

👎 Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

impl From<Error> for Error

Converting from a reqwest::Error is useful for quickly returning errors internally.

fn from(e: Error) -> Self

Performs the conversion.
