Struct PreprocessedText 

pub struct PreprocessedText {
    pub text: String,
    pub original_end: usize,
    pub mappings: Vec<LineMapping>,
}

Result of preprocessing text for multi-line concatenation.

The text field contains the original text unchanged, followed by any multiline-joined segments appended after a separator. This ensures:

1. Structural regex patterns (secret_key = "...") match in the original text.
2. Multiline-joined secrets ("sk-proj-" + "abc...") match in the appended segments.
3. No double-scanning or heuristic thresholds are needed.

Examples

use keyhog_scanner::multiline::PreprocessedText;

let value = PreprocessedText::passthrough("secret");
assert_eq!(value.line_for_offset(0), Some(1));

Fields

text: String

Original text + appended multiline-joined segments

original_end: usize

Byte offset where the appended joined segments start (= original text length)

mappings: Vec<LineMapping>

Mapping from offsets in text to original line numbers

Implementations

impl PreprocessedText

pub fn line_for_offset(&self, offset: usize) -> Option<usize>

Get the original line number for a given offset in the joined text. Map a byte offset in preprocessed text back to an original line number.

Examples

use keyhog_scanner::multiline::PreprocessedText;

let value = PreprocessedText::passthrough("secret");
assert_eq!(value.line_for_offset(0), Some(1));

pub fn passthrough(text: &str) -> Self

Create a passthrough (no preprocessing) — one mapping per line. Build a preprocessed representation with a one-line identity mapping.

Examples

use keyhog_scanner::multiline::PreprocessedText;

let value = PreprocessedText::passthrough("secret");
assert_eq!(value.text, "secret");
