Struct Config 

pub struct Config {
    pub workspace_root: PathBuf,
    pub crate_dir: PathBuf,
    pub package: String,
    pub target: Target,
    pub watch_paths: Vec<PathBuf>,
    pub bind_addr: SocketAddr,
    pub dev_token: Option<String>,
    pub hot_patch_mode: HotPatchMode,
    pub android: Option<AndroidParams>,
    pub ios: Option<IosParams>,
}

Where the dev loop should run, what to build, and how to behave. Constructed by whisker-cli from CLI flags + the user’s whisker.rs (via the cli’s manifest/probe pipeline); or by an editor plugin / test harness directly.

Flat params, not Config. Anything platform-specific lives inside AndroidParams / IosParams as simple strings and paths — the dev-server intentionally doesn’t depend on whisker-config. Translating the user’s configure(&mut Config) into these fields is the cli’s job.

Fields

workspace_root: PathBuf

Workspace root (Cargo.toml with [workspace]). Used by whisker-build invocations + RUSTC capture directories.

crate_dir: PathBuf

User-crate directory (Cargo.toml with [package]). This is what whisker run --manifest-path resolves to; for in-workspace examples it’s examples/<pkg>/, for an external user it’s wherever they keep their app.

package: String

User-crate package name (e.g. “podcast”).

target: Target

Where the rebuilt artifact gets installed + launched.

watch_paths: Vec<PathBuf>

Directories to watch for source changes. Empty defaults to <crate_dir>/src.

bind_addr: SocketAddr

Address the WebSocket server binds.

dev_token: Option<String>

Shared dev-session token. When Some, the WebSocket server only arms the patch channel for a client whose hello carries the matching token, and the cli delivers it to the device (iOS env / Android system property). None runs unauthenticated (the prior behaviour). whisker run generates a random one per session.

hot_patch_mode: HotPatchMode

Strategy for reflecting code edits onto the running app.

android: Option<AndroidParams>

Android install / launch params. Required iff target == Target::Android; absent for other targets.

ios: Option<IosParams>

iOS install / launch params. Required iff target == Target::IosSimulator; absent for other targets.

Implementations

impl Config

pub fn defaults_for( workspace_root: PathBuf, package: String, target: Target, ) -> Self

A starting point with sensible defaults; callers override fields.

Trait Implementations

impl Clone for Config

fn clone(&self) -> Config

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Config

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

Formats the value using the given formatter.
