Function sauron::prelude::styles_flag

pub fn styles_flag<V, MSG, P>(
    trio: P
) -> Attribute<&'static str, &'static str, AttributeValue<MSG>> where
    V: Into<Value> + Clone,
    P: AsRef<[(&'static str, V, bool)]>, 

A helper function which creates a style attribute by assembling only the parts that passed the boolean flag.

Examples

use sauron::prelude::*;

let is_active = true;
let display:Attribute<()> = styles_flag([
        ("display", "block", is_active),
        ("display", "none", !is_active),
    ]);

This could also be written as

use sauron::prelude::*;

let is_active = true;
let display:Attribute<()> =
    styles([("display", if is_active { "block" }else{ "none" })]);
