Struct WasmExecutionLimits 

pub struct WasmExecutionLimits {
    pub max_fuel: Option<u64>,
    pub max_memory_bytes: Option<u64>,
    pub max_stack_bytes: Option<u64>,
    pub prewarm_timeout_ms: Option<u64>,
    pub runner_heap_limit_mb: Option<u32>,
}

Per-execution WebAssembly runtime limits, carried as typed fields rather than AGENTOS_WASM_* env vars. Populated by the sidecar from the per-VM kernel ResourceLimits (originating from CreateVmConfig on the BARE wire); None selects “unlimited / engine default”. See the env-vs-wire rule in crates/sidecar/CLAUDE.md.

Fields

max_fuel: Option<u64>

Fuel budget, enforced as a wall-clock timeout (ms) by the WASI runtime.

max_memory_bytes: Option<u64>

Linear-memory cap in bytes, validated against the module’s declared initial/maximum memory before execution.

max_stack_bytes: Option<u64>

Stack cap in bytes. Validated from the typed wire value so bad config fails closed; runtime V8 stack-limit enforcement is a follow-up — see [resolve_wasm_stack_limit_bytes].

prewarm_timeout_ms: Option<u64>

Best-effort warmup/compile-cache timeout in ms.

runner_heap_limit_mb: Option<u32>

V8 heap cap for the trusted JS runner isolate that hosts WASI/WASM.

Trait Implementations

impl Clone for WasmExecutionLimits

fn clone(&self) -> WasmExecutionLimits

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for WasmExecutionLimits

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

Formats the value using the given formatter.

impl Default for WasmExecutionLimits

fn default() -> WasmExecutionLimits

Returns the “default value” for a type.

impl Eq for WasmExecutionLimits

impl PartialEq for WasmExecutionLimits

fn eq(&self, other: &WasmExecutionLimits) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
