Enum FileReadErrorCause

#[non_exhaustive]
pub enum FileReadErrorCause {
    IoError(Error),
    ParseError(ParseError),
}

The cause of a FileRead error

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.

IoError(Error)

Caused by an io error

ParseError(ParseError)

Caused by a parse error

Trait Implementations

impl Debug for FileReadErrorCause

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

Formats the value using the given formatter.

impl Display for FileReadErrorCause

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

Formats the value using the given formatter.

impl Error for FileReadErrorCause

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.

impl From<Error> for FileReadErrorCause

fn from(source: Error) -> Self

Converts to this type from the input type.

impl From<ParseError> for FileReadErrorCause

fn from(source: ParseError) -> Self

Converts to this type from the input type.

impl PartialEq for FileReadErrorCause

fn eq(&self, other: &Self) -> bool

Tests for self and other values to be equal, and is used by ==.

const fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
