Luau compiler

Implementations

impl Compiler

pub const fn new() -> Self

Creates Luau compiler instance with default options

pub const fn set_optimization_level(self, level: u8) -> Self

Sets Luau compiler optimization level.

Possible values:

• 0 - no optimization
• 1 - baseline optimization level that doesn’t prevent debuggability (default)
• 2 - includes optimizations that harm debuggability such as inlining

pub const fn set_debug_level(self, level: u8) -> Self

Sets Luau compiler debug level.

Possible values:

• 0 - no debugging support
• 1 - line info & function names only; sufficient for backtraces (default)
• 2 - full debug info with local & upvalue names; necessary for debugger

pub const fn set_type_info_level(self, level: u8) -> Self

Sets Luau type information level used to guide native code generation decisions.

Possible values:

• 0 - generate for native modules (default)
• 1 - generate for all modules

pub const fn set_coverage_level(self, level: u8) -> Self

Sets Luau compiler code coverage level.

Possible values:

• 0 - no code coverage support (default)
• 1 - statement coverage
• 2 - statement and expression coverage (verbose)

pub fn set_mutable_globals(self, globals: Vec<String>) -> Self

Sets a list of globals that are mutable.

It disables the import optimization for fields accessed through these.

pub fn set_userdata_types(self, types: Vec<String>) -> Self

Sets a list of userdata types that will be included in the type information.

pub fn compile(&self, source: impl AsRef<[u8]>) -> Result<Vec<u8>>

Compiles the source into bytecode.

Returns Error::SyntaxError if the source code is invalid.

Trait Implementations

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

Performs copy-assignment from source.

impl Debug for Compiler

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

impl Default for Compiler

fn default() -> Self

Returns the “default value” for a type.
