Struct JsRuntimeConfig 

pub struct JsRuntimeConfig {
    pub platform: JsRuntimePlatform,
    pub module_resolution: JsModuleResolution,
    pub allowed_builtins: Option<Vec<String>>,
    pub snapshot_userland_code: Option<String>,
}

Guest JavaScript host-environment configuration.

Selects which globals/builtins/module-resolution surface guest JS sees, modeled on esbuild’s platform. Omitting this preserves full Node.js emulation (platform = node).

Fields

platform: JsRuntimePlatform

Which host environment to emulate for guest JS. Default node.

module_resolution: JsModuleResolution

How bare import specifiers resolve. Independent of platform. Default node.

allowed_builtins: Option<Vec<String>>

Node builtin-module allow-list. Only valid when platform = node. None => engine default allow-list. Some([]) => deny all builtins. Some([..]) => exactly those.

snapshot_userland_code: Option<String>

Optional userland JS (an esbuild IIFE, e.g. a bundled agent SDK) to evaluate into the per-sidecar V8 startup snapshot alongside the bridge, so it is loaded once per sidecar and reused across sessions instead of re-imported on every execution. The snapshot is cached process-wide keyed by sha256(bridge + this code). Trusted client config; None keeps the bridge-only snapshot. Must be snapshot-safe (no native/External handles, fds, timers, or non-deterministic reads at module-init).

Trait Implementations

impl Clone for JsRuntimeConfig

fn clone(&self) -> JsRuntimeConfig

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for JsRuntimeConfig

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

Formats the value using the given formatter.

impl Default for JsRuntimeConfig

fn default() -> JsRuntimeConfig

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for JsRuntimeConfig

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for JsRuntimeConfig

impl PartialEq for JsRuntimeConfig

fn eq(&self, other: &JsRuntimeConfig) -> 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 JsRuntimeConfig

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl StructuralPartialEq for JsRuntimeConfig

impl TS for JsRuntimeConfig

const DOCS: Option<&'static str>

JSDoc comment to describe this type in TypeScript - when TS is derived, docs are automatically read from your doc comments or #[doc = ".."] attributes

type WithoutGenerics = JsRuntimeConfig

If this type does not have generic parameters, then WithoutGenerics should just be Self. If the type does have generic parameters, then all generic parameters must be replaced with a dummy type, e.g ts_rs::Dummy or (). The only requirement for these dummy types is that EXPORT_TO must be None.

fn ident() -> String

Identifier of this type, excluding generic parameters.

fn name() -> String

Name of this type in TypeScript, including generic parameters

fn decl_concrete() -> String

Declaration of this type using the supplied generic arguments. The resulting TypeScript definition will not be generic. For that, see TS::decl(). If this type is not generic, then this function is equivalent to TS::decl().

fn decl() -> String

Declaration of this type, e.g. type User = { user_id: number, ... }. This function will panic if the type has no declaration.

fn inline() -> String

Formats this types definition in TypeScript, e.g { user_id: number }. This function will panic if the type cannot be inlined.

fn inline_flattened() -> String

Flatten a type declaration.
This function will panic if the type cannot be flattened.

fn visit_generics(v: &mut impl TypeVisitor)

where Self: 'static,

Iterates over all type parameters of this type.

fn output_path() -> Option<&'static Path>

Returns the output path to where T should be exported.
The returned path does not include the base directory from TS_RS_EXPORT_DIR.

fn visit_dependencies(v: &mut impl TypeVisitor)

where Self: 'static,

Iterates over all dependency of this type.

fn dependencies() -> Vec<Dependency>

where Self: 'static,

Resolves all dependencies of this type recursively.

fn export() -> Result<(), ExportError>

where Self: 'static,

Manually export this type to the filesystem. To export this type together with all of its dependencies, use TS::export_all.

fn export_all() -> Result<(), ExportError>

where Self: 'static,

Manually export this type to the filesystem, together with all of its dependencies.
To export only this type, without its dependencies, use TS::export.

fn export_all_to(out_dir: impl AsRef<Path>) -> Result<(), ExportError>

where Self: 'static,

Manually export this type into the given directory, together with all of its dependencies.
To export only this type, without its dependencies, use TS::export.

fn export_to_string() -> Result<String, ExportError>

where Self: 'static,

Manually generate bindings for this type, returning a String.
This function does not format the output, even if the format feature is enabled.

fn default_output_path() -> Option<PathBuf>

Returns the output path to where T should be exported.
