Struct ModelIndex 

#[non_exhaustive]
pub struct ModelIndex {
    pub columns: &'static [&'static str],
    pub unique: bool,
}

An index a model declares with #[model(index(a, b))] or #[model(unique(a))].

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

columns: &'static [&'static str]

The indexed columns, in order.

unique: bool

Whether the index is unique.
