Struct Reducer 

pub struct Reducer { /* private fields */ }

Reducer is a native-only utility for reducing Luau source code while preserving a bug. It is not portable to wasm32-unknown-unknown.

Implementations

impl Reducer

pub fn delete_child_statements_ast_stat_block_usize( &mut self, block: *mut AstStatBlock, chunk_count: usize, ) -> (bool, usize)

impl Reducer

pub fn delete_child_statements_ast_stat_block( &mut self, b: *mut AstStatBlock, ) -> bool

impl Reducer

pub fn generate_spans(&self, size: usize, chunks: usize) -> Vec<(Span, Span)>

impl Reducer

pub fn get_nested_stats(&self, stat: *mut AstStat) -> Vec<*mut AstStat>

impl Reducer

pub fn pruned_span( &self, block: *mut AstStatBlock, span1: Span, span2: Span, ) -> Vec<*mut AstStat>

impl Reducer

pub fn read_line(&self, f: *mut c_void) -> String

impl Reducer

pub fn reallocate_statements( &mut self, statements: &Vec<*mut AstStat>, ) -> *mut *mut AstStat

Move new body data into allocator-managed storage so that it’s safe to keep around longterm. C++ (CLI/src/Reduce.cpp:233-239):

AstStat** newData = static_cast<AstStat**>(allocator.allocate(sizeof(AstStat*) * statements.size()));
std::copy(statements.data(), statements.data() + statements.size(), newData);
return newData;

The pointers are copied into arena storage owned by self.allocator, which outlives the Reducer, so the returned pointer stays valid for the rest of the run.

Trait Implementations

impl Debug for Reducer

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

Formats the value using the given formatter.

impl Default for Reducer

fn default() -> Self

Returns the “default value” for a type.
