Enum Error 

#[non_exhaustive]
pub enum Error {
    Io {
        path: String,
        source: Error,
    },
    Json {
        format: &'static str,
        message: String,
    },
    FormatRead {
        format: &'static str,
        message: String,
    },
    UnknownFormat(String),
}

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.

Implementations

impl Error

pub fn code(&self) -> &'static DiagnosticInfo

The registry entry for this error. The match is exhaustive over the variant set, so a new variant must be coded here before it compiles.

pub fn category(&self) -> ErrorCategory

Classify this error onto the five tokens every powerio surface uses.

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, __formatter: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

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

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.
