Trait ColumnCollectionExt 

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

Required Methods

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

Filter columns to only include those with the specified flag

Arguments

• flag - The column flag to filter by

Returns

A new Arc containing only columns that have the specified flag

fn exclude( &self, flag: ColumnFlag, ) -> Arc<IndexMap<String, Arc<dyn ColumnLike>>>

Filter columns to exclude those with the specified flag

Arguments

• flag - The column flag to filter out

Returns

A new Arc containing only columns that do not have the specified flag

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
