Enum ReverseApplyError 

pub enum ReverseApplyError {
    EmptyDiff,
    TooLarge,
    EmptyNewSide {
        hunk: usize,
    },
    NoMatch {
        hunk: usize,
    },
    Ambiguous {
        hunk: usize,
    },
    OverlappingSpans,
}

Exact reversal failure. Every variant refuses the whole file: partial reversal would silently corrupt content the evidence cannot reproduce.

Variants

EmptyDiff

No hunks to reverse.

TooLarge

Current content exceeds MAX_REVERSE_FILE_BYTES.

EmptyNewSide

Hunk has no new-side lines, so no content anchors its position.

Fields

hunk: usize

Zero-based hunk index.

NoMatch

The hunk’s new-side block does not occur in the current content: the file changed since the recorded edit.

Fields

hunk: usize

Zero-based hunk index.

Ambiguous

The hunk’s new-side block occurs more than once: reversing would guess which occurrence the recorded edit produced.

Fields

hunk: usize

Zero-based hunk index.

OverlappingSpans

Matched spans overlap or run out of order.

impl Eq for ReverseApplyError

impl Error for ReverseApplyError

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.
