Struct LaunchContext 

#[non_exhaustive]
pub struct LaunchContext {
    pub plugin_dirs: Vec<PathBuf>,
    pub config_root: Option<PathBuf>,
    pub cache_root: Option<PathBuf>,
    pub runtime_load: RuntimeLoadOptions,
    pub startup_started_at: Instant,
}

Startup inputs used to assemble runtime services and locate on-disk state.

This is launch-time provenance for the running host. It is kept separate from RuntimeContext because callers may need to rebuild caches or plugin services from the same startup inputs after config changes.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

plugin_dirs: Vec<PathBuf>

Explicit plugin directories requested by the caller at launch time.

config_root: Option<PathBuf>

Optional config-root override for runtime config discovery.

cache_root: Option<PathBuf>

Optional cache-root override for runtime state and caches.

runtime_load: RuntimeLoadOptions

Flags controlling which runtime config sources are consulted.

startup_started_at: Instant

Timestamp captured before startup work begins.

Implementations

impl LaunchContext

pub fn new( plugin_dirs: Vec<PathBuf>, config_root: Option<PathBuf>, cache_root: Option<PathBuf>, runtime_load: RuntimeLoadOptions, ) -> Self

Creates launch-time provenance for one host bootstrap attempt.

pub fn with_plugin_dir(self, plugin_dir: impl Into<PathBuf>) -> Self

Appends one explicit plugin directory.

pub fn with_plugin_dirs( self, plugin_dirs: impl IntoIterator<Item = PathBuf>, ) -> Self

Replaces the explicit plugin directory list.

pub fn with_config_root(self, config_root: Option<PathBuf>) -> Self

Sets the config root override.

pub fn with_cache_root(self, cache_root: Option<PathBuf>) -> Self

Sets the cache root override.

pub fn with_runtime_load(self, runtime_load: RuntimeLoadOptions) -> Self

Replaces the runtime-load flags carried by the launch context.

pub fn with_startup_started_at(self, startup_started_at: Instant) -> Self

Replaces the captured startup timestamp.
