    // Required methods
    fn only(
        &self,
        flag: ColumnFlag,
    ) -> Arc<IndexMap<String, Arc<dyn ColumnLike>>> ;

Extension trait for filtering collections of columns

This trait provides convenient methods for filtering columns by flags, allowing for fluent API usage.

Examples

use vantage_table::{ColumnCollectionExt, ColumnFlag};

// Get only visible columns (exclude hidden)
let visible = table.columns().exclude(ColumnFlag::Hidden);

// Get only mandatory columns
let mandatory = table.columns().only(ColumnFlag::Mandatory);

// Chain filters
let visible_mandatory = table.columns()
    .exclude(ColumnFlag::Hidden)
    .only(ColumnFlag::Mandatory);
