Struct iceberg::spec::ViewMetadata
source · pub struct ViewMetadata { /* private fields */ }
Expand description
Fields for the version 1 of the view metadata.
We assume that this data structure is always valid, so we will panic when invalid error happens. We check the validity of this data structure when constructing.
