Enum HmiConfig 

pub enum HmiConfig {
    Cog {
        dist: String,
        debug_url: Option<String>,
    },
    Pocket {
        bundle: String,
        pak: String,
        logical_width: u32,
        logical_height: u32,
    },
}

Compile-time HMI carrier the builder injects as environment variables before invoking the application cargo build. The consuming runtime crate reads them with option_env! at compile time, so the values are on-target paths resolved beneath [profile] deploy_root — the build host never dereferences them.

The engine tag selects which variables are emitted:

• Cog: consortium-hmi-webkit serves a dist directory.
• Pocket: consortium-hmi-pocket loads a bundle + pak.

Variants

Cog

Cog/WPE WebKit shell serving a static dist directory via csti://.

Fields

dist: String

On-target directory the deployed application serves assets from; becomes CONSORTIUM_HMI_DIST.

debug_url: Option<String>

Dev-server URL loaded directly in debug builds; when absent, debug builds fall back to the csti:// static handler.

Pocket

Native PocketJS shell loading a built bundle + pak from on-target paths.

Fields

bundle: String

On-target path of the PocketJS <app>.js bundle; becomes CONSORTIUM_HMI_POCKET_BUNDLE.

pak: String

On-target path of the PocketJS <app>.pak; becomes CONSORTIUM_HMI_POCKET_PAK.

logical_width: u32

Logical PocketJS viewport width in pixels.

logical_height: u32

Logical PocketJS viewport height in pixels.

Implementations

impl HmiConfig

pub fn from_hmi(hmi: &Hmi, deploy_root: &str) -> Self

Builds the compile-time HMI carrier from the parsed [hmi] section.

Because the build host and the target are different machines, every value is an on-target path a downstream packaging recipe installs assets to. Relative install locations are resolved beneath deploy_root (the manifest’s [profile] deploy_root convention): Cog serves {deploy_root}/www, and PocketJS loads {deploy_root}/hmi/<app>.{js,pak}.

Callers must have validated hmi (see Hmi::validate); a PocketJS section without app falls back to an empty name here.

pub fn env_pairs(&self) -> Vec<(String, String)>

Environment variables the builder injects for this config.

Consuming crates read these with option_env! at compile time. For Cog, CONSORTIUM_HMI_DEBUG_URL is emitted only when set, so its absence lets debug builds fall back to the static csti:// handler.
