Trait automatically implemented for tuples of TableColumns.

This trait is implemented for tuples of 1 to 12 columns via macros. You don’t need to implement this trait manually.

Example

// Single column
let cols1 = (Col1,);

// Multiple columns (tuple)
let cols2 = (Col1, Col2);

Required Methods

fn column_names(&self) -> Vec<String>

Returns the names of all columns.

fn headers( &self, ) -> Vec<Box<dyn Fn(&TableContext<Self>, Vec<Attribute>) -> Element + '_>>

Returns header renderers for all columns.

fn columns( &self, ) -> Vec<Box<dyn Fn(&TableContext<Self>, &R, Vec<Attribute>) -> Element + '_>>

Returns cell renderers for all columns.

fn filter(&self, row: &R) -> bool

Returns true if the row passes all column filters.

fn compare(&self) -> Vec<Box<dyn Fn(&R, &R) -> Ordering + '_>>

Returns comparators for all columns.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
