Error returned by fallible PieceTable compatibility APIs.

Variants

InvalidPieceRange

A piece points outside of its backing buffer.

Fields

buffer_type: BufferType

Backing buffer selected by the piece.

start: usize

Byte start recorded in the piece.

byte_length: usize

Byte length recorded in the piece.

buffer_len: usize

Current byte length of the selected backing buffer.

InvalidPieceUtf8

A piece range is not valid UTF-8.

Fields

buffer_type: BufferType

Backing buffer selected by the piece.

start: usize

Byte start recorded in the piece.

byte_length: usize

Byte length recorded in the piece.

Trait Implementations

impl Clone for PieceTableError

fn clone(&self) -> PieceTableError

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for PieceTableError

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

Formats the value using the given formatter.

impl Display for PieceTableError

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

Formats the value using the given formatter.

impl Eq for PieceTableError

impl Error for PieceTableError

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 PartialEq for PieceTableError

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

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

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

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