AlterCollectionFunction()

Alters a function attached to a collection schema.

pub async fn alter_collection_function(&self, request: AlterCollectionFunctionRequest) -> Result<()>

This request type is deprecated: Milvus 3.0 and later do not support altering a function separately. Use AddFunctionFieldRequest and DropFunctionFieldRequest instead.
