Struct ScriptRewriter 

pub struct ScriptRewriter { /* private fields */ }

Pre-compiled Rhai script used as a per-match replacement callback.

Implementations

impl ScriptRewriter

pub fn from_source(source: &str) -> Result<Self>

Compile source directly. Returns Error::ScriptParse on syntax errors.

pub fn from_file(path: &Path) -> Result<Self>

Read the script from path and compile it.

pub fn fresh(&self) -> Self

Build a sibling rewriter that shares the compiled AST with self but owns a fresh sandboxed engine. Rhai Engine is !Sync, so parallel pipelines that want to evaluate the same script on multiple worker threads call fresh() per worker (e.g. via rayon::par_iter().map_init(|| script.fresh(), ...)).

pub fn replace(&self, captures: &[&str]) -> Result<String>

Evaluate the script with captures (index 0 = full match) and return the resulting replacement string.

Trait Implementations

impl Debug for ScriptRewriter

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

Formats the value using the given formatter.
