Struct Limits 

pub struct Limits {
    pub macro_time_budget: Duration,
    pub hook_time_budget: Duration,
    pub memory_limit_bytes: usize,
    pub max_stack_bytes: usize,
}

Resource limits enforced on each JavaScript invocation.

Every field is applied to the engine that executes a single macro or hook invocation (see crate::MacroRuntime).

Fields

macro_time_budget: Duration

Wall-clock budget for macro invocations (crate::MacroRuntime::run_macro).

Enforced by a deadline-based interrupt handler: once the deadline passes, the engine aborts the script with the QuickJS "interrupted" error.

hook_time_budget: Duration

Wall-clock budget for post-compile hook invocations (crate::MacroRuntime::run_hook).

memory_limit_bytes: usize

Maximum engine memory in bytes (JS_SetMemoryLimit semantics).

When the engine’s tracked allocations exceed the limit, the script aborts with the "out of memory" error.

max_stack_bytes: usize

Maximum JavaScript stack size in bytes (JS_SetMaxStackSize semantics).

Deep recursion aborts with "Maximum call stack size exceeded".
