Error type for editor buffer validation, range operations, and file I/O.

Variants

OutOfBounds

The specified byte offset is out of document bounds.

Fields

offset: usize

The requested byte offset.

len: usize

The total length of the document in bytes.

InvalidRow

The specified row index is out of document line bounds.

Fields

row: usize

The requested row index.

total_lines: usize

The total number of lines in the document.

InvalidRange

The range is invalid because start offset exceeds end offset or document bounds.

Fields

range: Range<usize>

The requested byte range.

len: usize

The total length of the document in bytes.

InvalidCharBoundary

The byte offset does not land on a valid UTF-8 character boundary.

Fields

offset: usize

The invalid byte offset.

EmptySearchPattern

A search was attempted with an empty pattern.

InvalidRegex

A regex search pattern failed to compile.

Fields

pattern: String

The offending regex source.

message: String

The underlying regex engine error message.

Io(Error)

An I/O error occurred during file reading or writing.

Trait Implementations

impl Debug for EditorError

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

Formats the value using the given formatter.

impl Display for EditorError

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

Formats the value using the given formatter.

impl Error for EditorError

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 EditorError

fn from(source: Error) -> Self

Converts to this type from the input type.
