Struct LuaMiddleware 

pub struct LuaMiddleware { /* private fields */ }

SpawnerLayer that runs Lua source as a before-gate and/or an after-transform around a spawn, executed on a pooled AsyncIslePool VM. See the module doc for the exact function shapes expected of before_src / after_src.

Implementations

impl LuaMiddleware

pub fn new() -> Self

Empty layer — no before/after hooks, default pool.

pub fn before(self, src: impl Into<String>) -> Self

Sets the before-hook source (function(ctx_table) ... end). Raising from this function rejects the spawn.

pub fn after(self, src: impl Into<String>) -> Self

Sets the after-hook source (function(ctx_table, result_table) return result end). Its return value replaces the worker’s result.

pub fn with_pool(self, pool: Arc<AsyncIslePool>) -> Self

Inject an externally-built AsyncIslePool. Useful when the caller wants to share a pool with another Lua layer or carry VM initialisation across calls.

Trait Implementations

impl Clone for LuaMiddleware

fn clone(&self) -> LuaMiddleware

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Default for LuaMiddleware

fn default() -> LuaMiddleware

Returns the “default value” for a type.

impl SpawnerLayer for LuaMiddleware

fn wrap(&self, inner: Arc<dyn SpawnerAdapter>) -> Arc<dyn SpawnerAdapter>

Wraps inner in this layer’s behaviour, returning a new SpawnerAdapter that delegates to inner (directly or via wrap_join) while adding this layer’s cross-cutting effect.
