Enum ctru::error::Error

#[non_exhaustive]
pub enum Error {
    Os(Result),
    Libc(String),
    ServiceAlreadyActive,
    OutputAlreadyRedirected,
    BufferTooShort {
        provided: usize,
        wanted: usize,
    },
    Other(String),
}

The generic error enum returned by ctru-rs functions.

This error enum supports parsing and displaying ctru_sys::Result codes.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Os(Result)

Raw ctru_sys::Result codes.

Libc(String)

Generic [libc] errors.

ServiceAlreadyActive

Requested service is already active and cannot be activated again.

OutputAlreadyRedirected

stdout is already being redirected.

BufferTooShort

Fields

provided: usize

Length of the buffer provided by the user.

wanted: usize

Size of the requested data (in bytes).

The buffer provided by the user to store some data is shorter than required.

Other(String)

An error that doesn’t fit into the other categories.

Implementations

impl Error

pub fn is_timeout(&self) -> bool

Check if the error is a timeout.

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

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

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 Error

fn from(value: Error) -> Self

Converts to this type from the input type.

impl From<ResultCode> for Error

fn from(err: ResultCode) -> Self

Converts to this type from the input type.

impl From<i32> for Error

fn from(err: Result) -> Self

Converts to this type from the input type.

impl<T> FromResidual<Error> for Result<T, Error>

fn from_residual(residual: Error) -> Self

🔬This is a nightly-only experimental API. (try_trait_v2)

Constructs the type from a compatible Residual type.
