Struct MetadataCtx

Source

pub struct MetadataCtx { /* private fields */ }

Expand description

Per-store data for the metadata extraction sandbox. Carries a fully-empty WasiCtx (no preopens, no env, no stdio mapping) so every WASI probe returns empty data — the empty context, not import-time link failure, is what isolates the plugin.
