Enum EditError 

pub enum EditError {
    NotFound {
        old: String,
    },
    NotUnique {
        old: String,
        count: usize,
    },
    NoOp,
    EmptyTarget,
    NoEdits,
    AnchorOutOfRange {
        start: usize,
        end: usize,
        lines: usize,
    },
    AnchorShifted,
}

Why a reconstruction could not be produced. Each variant is a deny at the gate; none of them may be absorbed into a plausible-looking string.

Variants

NotFound

The target does not occur in the content the edit was applied to. With MultiEdit this includes a target a PREVIOUS edit destroyed.

Fields

old: String

NotUnique

The target occurs more than once and replace_all was not set, so the tool cannot know which was meant. Replacing the first is the plausible guess and precisely the guess that fabricates a file.

Fields

old: String

count: usize

NoOp

old and new are identical — a caller mistake, not a no-op to absorb.

EmptyTarget

An empty target has no meaningful occurrence count; every position matches.

NoEdits

A mutation naming no edits is malformed, not a no-op.

AnchorOutOfRange

The anchor names lines the file does not have, or an inverted range. The family is describing a file we are not looking at.

Fields

start: usize

end: usize

lines: usize

AnchorShifted

An anchored edit follows one that changed the file’s line count, so its coordinates are ambiguous between two readings the capture does not distinguish: original-file numbering, or numbering in the file as the previous edits left it. Both agree until a line is added or removed, and then they disagree silently. Refusing is the only honest answer until a capture settles it.

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

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 PartialEq for EditError

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

Equality operator ==.

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

Inequality operator !=.
