Struct Replacement 

#[non_exhaustive]
pub struct Replacement {
    pub start: usize,
    pub end: usize,
    pub value: String,
}

A byte-range edit on the original source: replace content[start..end] with value.

Produced by span-based processors (Processor::process_to_edits) so a matched field value is replaced exactly where it appears in the source, leaving all surrounding bytes — quotes, comments, whitespace, key order, and the precise escaping of unrelated content — byte-for-byte intact. This is what makes structured sanitization both leak-free (the real bytes are hit, regardless of how the value was escaped) and fully format-preserving.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

start: usize

Start byte offset (inclusive) of the range to replace.

end: usize

End byte offset (exclusive) of the range to replace.

value: String

Replacement text (the sanitized token, already in the form it should take in the source — e.g. including surrounding quotes for a string).

Implementations

impl Replacement

pub fn new(start: usize, end: usize, value: impl Into<String>) -> Self

Create a replacement of the byte range start..end with value. The struct is #[non_exhaustive], so this is how custom processors build edits outside the crate.

Trait Implementations

impl Clone for Replacement

fn clone(&self) -> Replacement

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Replacement

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

Formats the value using the given formatter.

impl Eq for Replacement

impl PartialEq for Replacement

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

Equality operator ==.

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

Inequality operator !=.
