Struct AppendReducer 

pub struct AppendReducer<S: StateSchema, T: Clone + Send + Sync> {
    pub field_accessor: fn(&S) -> &[T],
    pub field_mutator: fn(&mut S, Vec<T>),
}

Append reducer for vector fields (like add_messages pattern)

This reducer appends new items to vector fields in the state. Useful for message history, steps history, etc.

Fields

field_accessor: fn(&S) -> &[T]

Function that reads the vector field from a state.

field_mutator: fn(&mut S, Vec<T>)

Function that writes the merged vector back into a state.

Trait Implementations

impl<S: StateSchema, T: Clone + Send + Sync> Reducer<S> for AppendReducer<S, T>

fn reduce(&self, current: &S, update: &S) -> S

Reduce current state with an update
