Trait DistinctExt 

pub trait DistinctExt<T: CellValue + Eq + Hash, S: Seedness>: Pipeline<T, S> {
    // Required method
    fn distinct(self) -> impl Materialize<T, S>;
}

Required Methods

fn distinct(self) -> impl Materialize<T, S>

Filter out values that have already been emitted (by Hash/Eq).

Example

use hyphae::{Cell, DistinctExt, Materialize, Mutable};

let source = Cell::new(0);
let distinct = source.clone().distinct().materialize();

source.set(1);
source.set(2);
source.set(1); // blocked - already seen
source.set(3);
source.set(2); // blocked - already seen

Dyn Compatibility

This trait is not dyn compatible.

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