Struct mlua::HookTriggers

pub struct HookTriggers {
    pub on_calls: bool,
    pub on_returns: bool,
    pub every_line: bool,
    pub every_nth_instruction: Option<u32>,
}

Determines when a hook function will be called by Lua.

Fields

on_calls: bool

Before a function call.

on_returns: bool

When Lua returns from a function.

every_line: bool

Before executing a new line, or returning from a function call.

every_nth_instruction: Option<u32>

After a certain number of VM instructions have been executed. When set to Some(count), count is the number of VM instructions to execute before calling the hook.

Performance

Setting this option to a low value can incur a very high overhead.
