Struct MultiVersionLinker 

pub struct MultiVersionLinker { /* private fields */ }

Per-major Linker cache.

Construct once at host startup (e.g., alongside the Engine), then call Self::linker_for on every plugin load.

Implementations

impl MultiVersionLinker

pub fn new(engine: Engine) -> Self

Construct a new cache over engine.

pub fn linker_for( &self, abi: &AbiRange, effective_caps: &CapabilitySet, ) -> Result<Arc<Linker<HostState>>, WasmError>

Resolve and return the Linker matching the plugin’s declared ABI range and effective capability set.

Probes SUPPORTED_MAJORS in order; the first major whose abi.matches(major) is true is selected. The corresponding build_scalar_linker_vN is invoked on cache miss; subsequent calls with the same (major, caps) return the cached Arc.

Errors

Returns WasmError::AbiUnsupported when no supported major matches the plugin’s abi range.

pub fn clear_cache(&self)

Reset the cache. Intended for tests; production callers don’t need to clear because cached linkers are immutable after build.

Trait Implementations

impl Debug for MultiVersionLinker

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

Formats the value using the given formatter.
