Struct WasmConfig 

pub struct WasmConfig {
    pub timeout_secs: u64,
    pub max_memory_bytes: u64,
    pub max_concurrent_calls: usize,
    pub max_wasm_size_bytes: u64,
    pub allow_call_schemes: String,
    pub max_stream_bytes: u64,
    pub max_instances: usize,
    pub max_tables: usize,
    pub max_table_elements: Option<usize>,
}

Configuration for a WASM plugin instance.

Parsed from URI query parameters or Camel.toml. Example URI: wasm:plugin.wasm?timeout=10&max-memory=52428800

Fields

timeout_secs: u64

Maximum execution time per guest call, in seconds.

max_memory_bytes: u64

Maximum linear memory the guest can allocate, in bytes. Enforced via wasmtime::StoreLimitsBuilder::memory_size.

max_concurrent_calls: usize

Maximum concurrent call_process executions per producer.

max_wasm_size_bytes: u64

Maximum .wasm file size in bytes. Files exceeding this are rejected before compilation to prevent DoS via pathologically large modules. Default: 10 MB.

allow_call_schemes: String

Comma-separated URI schemes the guest may call via camel_call/camel_poll. Empty string = deny all (fail-closed). Example: “log,direct,file”. Ignored for AuthorizationPolicy/SecurityPolicy worlds (always denied).

max_stream_bytes: u64

Maximum bytes for the streaming body bridge.

max_instances: usize

Maximum core instances per store. Default 10_000 (matches wasmtime).

max_tables: usize

Maximum tables per store. Default 10_000 (matches wasmtime).

max_table_elements: Option<usize>

Maximum table elements. None = no cap (wasmtime unlimited).

Implementations

impl WasmConfig

pub fn from_limits(limits: &WasmLimitsConfig) -> WasmConfig

Build concrete runtime config from optional Camel.toml WASM limits.

None values use runtime defaults matching WasmConfig::default(). This constructor is the single source of truth for WasmConfig defaults sourced from Camel.toml — no silent fallback lie elsewhere (ADR-0011).

pub fn from_uri(uri_without_scheme: &str) -> (String, WasmConfig)

Parse WasmConfig from the query portion of a WASM URI.

uri_without_scheme is everything after wasm:, e.g. plugins/my_processor.wasm?timeout=10&max-memory=52428800.

Returns (path, config) where path has no query string.

pub fn epoch_deadline(&self) -> u64

Convert the wall-clock timeout to an epoch deadline (number of ticks).

At 10ms per tick: deadline = timeout_secs * 100

pub fn epoch_interval(&self) -> Duration

The interval at which the epoch ticker thread increments the epoch.

pub fn epoch_interval_millis(&self) -> u64

Returns the configured epoch interval in milliseconds.

pub fn classify_error(&self, plugin_path: &Path, e: Error) -> WasmError

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.
