Struct LuaOptions

#[non_exhaustive]
pub struct LuaOptions {
    pub catch_rust_panics: bool,
    pub thread_pool_size: usize,
}

Controls Lua interpreter behavior such as Rust panics handling.

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.

catch_rust_panics: bool

Catch Rust panics when using pcall/xpcall.

If disabled, wraps these functions and automatically resumes panic if found. Also in Lua 5.1 adds ability to provide arguments to xpcall similar to Lua >= 5.2.

If enabled, keeps pcall/xpcall unmodified. Panics are still automatically resumed if returned to the Rust side.

Default: true

thread_pool_size: usize

Available on crate feature async only.

Max size of thread (coroutine) object pool used to execute asynchronous functions.

Default: 0 (disabled)
