Enum Priority 

pub enum Priority {
    Optional,
    Secondary,
    Essential,
}

What a column is worth when there is not room for all of them.

Ordered: Priority::Optional drops first, Priority::Essential never drops. This replaces addressing columns by position, which is what both webview apps do today and is a live bug rather than only verbosity. goingson hides mobile columns with nth-child(n+5) against a seven-column table, so inserting a column silently hides the wrong one.

Variants

Optional

Dropped first.

Secondary

Dropped once the optional columns are gone.

Essential

Never dropped. Without it the row does not identify itself.

Trait Implementations

impl PartialEq for Priority

fn eq(&self, other: &Priority) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

impl PartialOrd for Priority

fn partial_cmp(&self, other: &Priority) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool
