Struct BuildConfig 

pub struct BuildConfig<'a> {
    pub build_root: &'a Path,
    pub adapter_wasm: &'a Path,
    pub target: Option<&'a str>,
}

Knobs that don’t come from the wrapper inputs but are needed to actually drive cargo.

Fields

build_root: &'a Path

Root under which per-build directories live. Each unique (target_wit, behavior, strategy) gets a subdirectory so cargo’s incremental compile stays warm across runs.

adapter_wasm: &'a Path

Path to the wasi_snapshot_preview1 reactor adapter that wasm-tools component new uses to wrap the core module.

target: Option<&'a str>

Cargo target triple. Defaults to "wasm32-wasip1" if None.
