Enum Error

#[non_exhaustive]
pub enum Error {
    FileMissing,
    IndexTooLarge {
        given: usize,
        max: usize,
    },
    LineTooLarge {
        given: usize,
        max: usize,
    },
    ColumnTooLarge {
        given: usize,
        max: usize,
    },
    InvalidCharBoundary {
        given: usize,
    },
    Io(Error),
}

An enum representing an error that happened while looking up a file or a piece of content in that file.

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.

FileMissing

A required file is not in the file database.

IndexTooLarge

The file is present, but does not contain the specified byte index.

Fields

given: usize

max: usize

LineTooLarge

The file is present, but does not contain the specified line index.

Fields

given: usize

max: usize

ColumnTooLarge

The file is present and contains the specified line index, but the line does not contain the specified column index.

Fields

given: usize

max: usize

InvalidCharBoundary

The given index is contained in the file, but is not a boundary of a UTF-8 code point.

Fields

given: usize

Io(Error)

There was a error while doing IO.

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)>

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(err: Error) -> Error

Converts to this type from the input type.
