Trait StylePropReader 

pub trait StylePropReader {
    type State: Debug;
    type Type: Clone;

    // Required methods
    fn read(
        state: &mut Self::State,
        style: &Style,
        now: &Instant,
        request_transition: &mut bool,
    ) -> bool;
    fn get(state: &Self::State) -> Self::Type;
    fn new() -> Self::State;
}

Required Associated Types

type State: Debug

type Type: Clone

Required Methods

fn read( state: &mut Self::State, style: &Style, now: &Instant, request_transition: &mut bool, ) -> bool

Reads the property from the style. Returns true if the property changed.

fn get(state: &Self::State) -> Self::Type

fn new() -> Self::State

Dyn Compatibility

This trait is not dyn compatible.

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