pub enum Error {
    Io(Error),
    NotRegularFile,
    FileTooLarge,
    EmptyFilesCannotDiffer,
    EmptyLinesCannotDiffer,
    InvalidLineNumber,
    InvalidBytePosition,
    SearchAlreadyComplete,
}

An error returned by a core operation.

Variants

Io(Error)

NotRegularFile

The path does not identify a regular file.

FileTooLarge

A byte count, line count, or character position cannot fit in u64.

EmptyFilesCannotDiffer

Both supplied line counts are zero despite a reported mismatch.

EmptyLinesCannotDiffer

Both supplied line byte lengths are zero despite a reported mismatch.

InvalidLineNumber

A line-local operation was given line zero; its lines start at 1.

InvalidBytePosition

The byte position is zero or more than one past the selected line.

An absent line permits only byte position 1.

SearchAlreadyComplete

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 StdError + '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 Error

fn from(error: Error) -> Self

Converts to this type from the input type.
