Trait Evaluate

pub trait Evaluate<R>:
    Sized
    + Debug
    + 'static {
    type Error: Error + Send + Sync + 'static;

    // Required methods
    fn init(entry: &Entry, store: &R) -> Result<Self, Self::Error>;
    fn apply<'a, I: Iterator<Item = (&'a Oid, &'a Entry)>>(
        &mut self,
        entry: &Entry,
        concurrent: I,
        store: &R,
    ) -> Result<(), Self::Error>;
}

An object that can be built by evaluating a history.

Required Associated Types

type Error: Error + Send + Sync + 'static

Required Methods

fn init(entry: &Entry, store: &R) -> Result<Self, Self::Error>

Initialize the object with the first (root) history entry.

fn apply<'a, I: Iterator<Item = (&'a Oid, &'a Entry)>>( &mut self, entry: &Entry, concurrent: I, store: &R, ) -> Result<(), Self::Error>

Apply a history entry to the evaluated state.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
