Struct FixEdit 

pub struct FixEdit {
    pub span: Span,
    pub replacement: String,
}

A machine-applicable text replacement for autofixing diagnostics.

Fields

span: Span

The source span to replace.

replacement: String

The replacement text (empty string = deletion).

Implementations

impl FixEdit

pub fn dedupe_overlapping(edits: &[FixEdit]) -> Vec<FixEdit>

Sort edits right-to-left by start offset and drop any that overlap an already-accepted edit, returning the survivors in descending-start order — ready to splice right-to-left without invalidating earlier offsets. This is the single source of truth for the “apply all fixes, drop conflicts” policy that harn fmt, harn lint --fix, and the LSP on-save fixer must agree on byte-for-byte.

pub fn apply_all(source: &str, edits: &[FixEdit]) -> String

Apply edits to source, dropping overlaps via Self::dedupe_overlapping and splicing right-to-left. Callers that also need the accepted-edit list (e.g. to build LSP TextEdits) should call dedupe_overlapping directly.
