### Public features
### Users should opt in necessary features explicitly

## Flags to opt into certain optimizations. In most cases this won't expose new interfaces,
## but changes internal logics to perform differently. These flag should be turned on in combination with
## actual features. Refer build.rs for more details.

# In most cases, top-level features (i.e plugin, or plugin_host) will include this, so no need to

# and some other dependent feature need this, can be manually selected.
# refer binding_core_wasm for example: it has plugin_transform_host feature, but
