Enum ColumnSelection 

#[non_exhaustive]
pub enum ColumnSelection {
    All,
    #[non_exhaustive]
    Listed {
        names: Vec<String>,
    },
}

Which of the source’s columns a run profiled.

A projection that names a column the source lacks is refused before profiling, so a report with ColumnSelection::All that has no profile for a column shows the source has no such column, and one with ColumnSelection::Listed shows only that the caller did not select it.

Variants (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.

All

Every column of the source.

#[non_exhaustive]

Listed

Only the named columns.

Fields

Non-exhaustive enum variants could have additional fields added in future. Therefore, non-exhaustive enum variants cannot be constructed in external crates and cannot be matched against.

names: Vec<String>

The names as the caller gave them.
