Enum EditError 

pub enum EditError {
    Range(RangeError),
    OutOfBounds {
        end: usize,
        len: usize,
    },
    NotCharBoundary {
        offset: usize,
    },
    StaleEdit {
        expected: String,
        found: String,
    },
}

Error applying a DocumentChange to a source string.

Variants

Range(RangeError)

The change’s range is not a valid range (start > end).

OutOfBounds

The change’s range extends past the end of the source.

Fields

end: usize

The offending (exclusive) end offset.

len: usize

The source length in bytes.

NotCharBoundary

A range endpoint does not sit on a UTF-8 character boundary.

Fields

offset: usize

The offending byte offset.

StaleEdit

The change’s old_text does not match what the source actually contains at the range — the edit was built against a stale version of the document. Precondition failure, not a panic.

Fields

expected: String

What the change claimed the range contained.

found: String

What the source actually contains at the range.

Trait Implementations

impl Clone for EditError

fn clone(&self) -> EditError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for EditError

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

Formats the value using the given formatter.

impl Display for EditError

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

Formats the value using the given formatter.

impl Eq for EditError

impl Error for EditError

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<RangeError> for EditError

fn from(source: RangeError) -> Self

Converts to this type from the input type.

impl PartialEq for EditError

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

Equality operator ==.

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

Inequality operator !=.
