Ropey’s error type.

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.

ByteIndexOutOfBounds(usize, usize)

Indicates that the passed byte index was out of bounds.

Contains the index attempted and the actual length of the Rope/RopeSlice in bytes, in that order.

CharIndexOutOfBounds(usize, usize)

Indicates that the passed char index was out of bounds.

Contains the index attempted and the actual length of the Rope/RopeSlice in chars, in that order.

LineIndexOutOfBounds(usize, usize)

Indicates that the passed line index was out of bounds.

Contains the index attempted and the actual length of the Rope/RopeSlice in lines, in that order.

Utf16IndexOutOfBounds(usize, usize)

Indicates that the passed utf16 code-unit index was out of bounds.

Contains the index attempted and the actual length of the Rope/RopeSlice in utf16 code units, in that order.

ByteIndexNotCharBoundary(usize)

Indicates that the passed byte index was not a char boundary.

Contains the passed byte index.

ByteRangeNotCharBoundary(Option<usize>, Option<usize>)

Indicates that the passed byte range didn’t line up with char boundaries.

Contains the [start, end) byte indices of the range, in that order. When either the start or end are None, that indicates a half-open range.

ByteRangeInvalid(usize, usize)

Indicates that a reversed byte-index range (end < start) was encountered.

Contains the [start, end) byte indices of the range, in that order.

CharRangeInvalid(usize, usize)

Indicates that a reversed char-index range (end < start) was encountered.

Contains the [start, end) char indices of the range, in that order.

ByteRangeOutOfBounds(Option<usize>, Option<usize>, usize)

Indicates that the passed byte-index range was partially or fully out of bounds.

Contains the [start, end) byte indices of the range and the actual length of the Rope/RopeSlice in bytes, in that order. When either the start or end are None, that indicates a half-open range.

CharRangeOutOfBounds(Option<usize>, Option<usize>, usize)

Indicates that the passed char-index range was partially or fully out of bounds.

Contains the [start, end) char indices of the range and the actual length of the Rope/RopeSlice in chars, in that order. When either the start or end are None, that indicates a half-open range.

Trait Implementations

impl Clone for Error

fn clone(&self) -> Error

Returns a copy of the value.

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

Performs copy-assignment from source.

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.
