Expand description

columns are the constituent parts of tables. They consist of vectors holding elements of the same type. Types are differentiated via the variants of this enum.

Right now, 3 variants are supported:

  • Integer always a Vec<i64>
  • Float always a Vec<f64>
  • Text always a Vec<String> In the future, more variants may be added as necessary. As such, this enum is marked as #[non_exhaustive].

Variants (Non-exhaustive)

This enum is marked as non-exhaustive
Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Integer(Vec<i64>)

Float(Vec<f64>)

Text(Vec<String>)
