Struct WasmTransformConfig 

pub struct WasmTransformConfig {
    pub module: String,
    pub function: String,
    pub memory_limit_mb: u32,
    pub fuel_limit: u64,
    pub on_error: WasmOnError,
    pub reload_on_change: bool,
}

Configuration for the wasm transform.

Fields

module: String

Filesystem path to the precompiled .wasm module (absolute, or relative to the working directory). URLs are not supported in v1.

function: String

Name of the exported transform function. Default "transform".

memory_limit_mb: u32

Linear-memory cap for the module, in mebibytes. A record that grows memory past this limit fails that record (routed by on_error). Default 16. The practical lower bound for ~1 KB JSON records is ~8 MB.

fuel_limit: u64

wasmtime fuel budget per record — a deterministic CPU bound. A record that exhausts its fuel fails (routed by on_error). Default 10_000_000. Fuel is the effective CPU limit in v1 (there are no blocking host calls, so a wall-clock timeout would be redundant).

on_error: WasmOnError

What to do when a record fails inside the module (trap, fuel/memory exhaustion, ABI violation, or non-JSON output). Default fail.

reload_on_change: bool

Re-stat the module file’s mtime before each page; recompile and swap in the new module atomically at the page boundary if it changed. In-flight records within a page always use one module. Default false.

Trait Implementations

impl Clone for WasmTransformConfig

fn clone(&self) -> WasmTransformConfig

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for WasmTransformConfig

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for WasmTransformConfig

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl JsonSchema for WasmTransformConfig

fn schema_name() -> Cow<'static, str>

The name of the generated JSON Schema.

fn schema_id() -> Cow<'static, str>

Returns a string that uniquely identifies the schema produced by this type.

fn json_schema(generator: &mut SchemaGenerator) -> Schema

Generates a JSON Schema for this type.

fn inline_schema() -> bool

Whether JSON Schemas generated for this type should be included directly in parent schemas, rather than being re-used where possible using the $ref keyword.

impl Serialize for WasmTransformConfig

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
