Comprehensive configuration for all WASM service types.

Replaces the previous WasmHttpConfig with resource limits, capability declarations, networking controls, and storage configuration.

Fields

min_instances: u32

Minimum number of warm instances to keep ready

max_instances: u32

Maximum number of instances to scale to

idle_timeout: Duration

Time before idle instances are terminated

request_timeout: Duration

Maximum time for a single request

max_memory: Option<String>

Maximum linear memory (e.g., “64Mi”, “256Mi”)

max_fuel: u64

Maximum fuel (instruction count limit, 0 = unlimited)

epoch_interval: Option<Duration>

Epoch interval for cooperative preemption

capabilities: Option<WasmCapabilities>

Explicit capability grants (overrides world defaults when restricting)

allow_http_outgoing: bool

Allow outgoing HTTP requests (default: true)

allowed_hosts: Vec<String>

Allowed outgoing HTTP hosts (empty = all allowed)

allow_tcp: bool

Allow raw TCP sockets (default: false)

allow_udp: bool

Allow raw UDP sockets (default: false)

preopens: Vec<WasmPreopen>

Pre-opened directories (host path -> guest path)

kv_enabled: bool

Enable KV store access (default: true)

kv_namespace: Option<String>

KV store namespace (default: service name)

kv_max_value_size: u64

KV store max value size in bytes (default: 1MB)

secrets: Vec<String>

Secret names accessible to this WASM module

precompile: bool

Pre-compile on deploy to reduce cold start (default: true)

Trait Implementations

impl Clone for WasmConfig

fn clone(&self) -> WasmConfig

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for WasmConfig

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

Formats the value using the given formatter.

impl Default for WasmConfig

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for WasmConfig

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl From<WasmHttpConfig> for WasmConfig

fn from(old: WasmHttpConfig) -> Self

Converts to this type from the input type.

impl PartialEq for WasmConfig

fn eq(&self, other: &WasmConfig) -> 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.

impl Serialize for WasmConfig

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
