Variants

OffsetOutOfBounds

A byte offset lies beyond EOF.

Fields

offset: ByteOffset

len: ByteOffset

LineOutOfBounds

A zero-based line does not exist.

Fields

line: u32

line_count: usize

ByteColumnOutOfBounds

A byte column does not identify a byte or the final EOF position.

Fields

line: u32

column: u32

max_column: u32

CharacterOutOfBounds

An editor character lies beyond the logical end of its line.

Fields

line: u32

character: u32

max_character: u32

encoding: PositionEncoding

OffsetInsideLineTerminator

A byte offset falls between the CR and LF bytes of a CRLF terminator.

Fields

offset: ByteOffset

line: u32

MidCodePoint

A UTF-8 position falls within a multi-byte code point.

Fields

offset: ByteOffset

MidUtf16Surrogate

A UTF-16 position falls between the surrogate code units of an astral character.

Fields

line: u32

character: u32

InvalidUtf8

Editor conversion requires a valid UTF-8 source document.

Fields

valid_up_to: ByteOffset

error_len: Option<usize>

Trait Implementations

impl Clone for PositionError

fn clone(&self) -> PositionError

impl Eq for PositionError

impl Error for PositionError

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

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl From<PositionError> for DiagnosticReportError

fn from(source: PositionError) -> Self

Converts to this type from the input type.

impl PartialEq for PositionError

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

Equality operator ==.
