Struct 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.
