Struct RuntimeConfig 

pub struct RuntimeConfig {
    pub paths: DiscoveryPaths,
    pub host_overrides: HostOverrides,
}

Configuration passed to ExtensionRuntime::new.

Carries both the filesystem discovery paths and the HostOverrides bundle that every dispatch call injects into the wasmtime HostState. Callers that only need defaults (tests, simple CLI tools) can use RuntimeConfig::from_paths; production callers that need real i18n/secrets/HTTP backends chain RuntimeConfig::with_host_overrides before handing the config to the runtime.

Fields

paths: DiscoveryPaths

host_overrides: HostOverrides

Host-function overrides threaded into every WASM dispatch. Defaults to HostOverrides::default() (key-translator, empty secrets, no HTTP client, empty allow-list, no broker weak ref). Production callers replace this via RuntimeConfig::with_host_overrides or the ergonomic ExtensionRuntime::with_host_overrides builder.

Implementations

impl RuntimeConfig

pub fn from_paths(paths: DiscoveryPaths) -> Self

Construct a config from discovery paths, using production-safe HostOverrides::default() (no HTTP client, empty secrets/i18n).

pub fn with_host_overrides(self, overrides: HostOverrides) -> Self

Replace the HostOverrides bundle. Returns self for builder-style chaining:

let config = RuntimeConfig::from_paths(paths)
    .with_host_overrides(production_overrides);
