Enum Error 

#[non_exhaustive]
pub enum Error<M: Measurable> {
    IndexOutOfBounds(usize, usize),

AnyRope’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.

IndexOutOfBounds(usize, usize)

Indicates that the passed index was out of bounds.

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

MeasureOutOfBounds(M::Measure, M::Measure)

Indicates that the passed measure was out of bounds.

Contains the index attempted and the actual measure of the Rope<M>/RopeSlice<M>, in that order.

IndexRangeInvalid(usize, usize)

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

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

MeasureRangeInvalid(Option<M::Measure>, Option<M::Measure>)

Indicates that a reversed measure range (end < start) was encountered.

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

IndexRangeOutOfBounds(Option<usize>, Option<usize>, usize)

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

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

MeasureRangeOutOfBounds(Option<M::Measure>, Option<M::Measure>, M::Measure)

Indicates that the passed measure range was partially or fully out of bounds.

Contains the [start, end) measures of the range and the actual measure of the Rope<M>/RopeSlice<M>, in that order. When either the start or end are None, that indicates a half-open range.

Trait Implementations

impl<M: Clone + Measurable> Clone for Error<M>

where M::Measure: Clone,

fn clone(&self) -> Error<M>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<M: Measurable> Debug for Error<M>

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

Formats the value using the given formatter.

impl<M: Measurable> Display for Error<M>

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

Formats the value using the given formatter.

impl<M: Measurable> Error for Error<M>

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
