Trait Update 

pub trait Update {
    type Key: Ord + Clone + 'static;
    type Val: Ord + Clone + 'static;
    type Time: Lattice + Timestamp;
    type Diff: Ord + Semigroup + 'static;
}

A type that names constituent update types.

Required Associated Types

type Key: Ord + Clone + 'static

Key by which data are grouped.

type Val: Ord + Clone + 'static

Values associated with the key.

type Time: Lattice + Timestamp

Time at which updates occur.

type Diff: Ord + Semigroup + 'static

Way in which updates occur.

Dyn Compatibility

This trait is dyn compatible.

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

Implementations on Foreign Types

impl<K, V, T, R> Update for ((K, V), T, R)

where K: Ord + Clone + 'static, V: Ord + Clone + 'static, T: Lattice + Timestamp, R: Ord + Semigroup + 'static,

type Key = K

type Val = V

type Time = T

type Diff = R
