Struct BatchTree 

pub struct BatchTree<A: Adapter> { /* private fields */ }

A batch collector for aggregating and optimizing multiple mutations.

BatchTree is used internally to collect multiple mutations and optimize them before creating the final mutation. It can merge consecutive append operations and eliminate redundant mutations.

Example

use morphix::{BatchTree, JsonAdapter, Mutation, MutationKind};
use serde_json::json;

let mut batch = BatchTree::<JsonAdapter>::new();

// Load multiple mutations
batch.load(Mutation {
    path: vec!["field".into()].into(),
    kind: MutationKind::Replace(json!(1)),
}).unwrap();

// Dump optimized mutations
let optimized = batch.dump();

Implementations

impl<A: Adapter> BatchTree<A>

pub fn new() -> Self

Creates a new empty batch.

pub fn load(&mut self, mutation: Mutation<A>) -> Result<(), MutationError>

Loads a Mutation into the batch, potentially merging with existing mutations.

pub fn dump(&mut self) -> Option<Mutation<A>>

Dumps all accumulated mutations as a single optimized mutation.

• Returns None if no mutations have been accumulated.
• Returns a single mutation if only one mutation exists.
• Returns a Batch mutation if multiple mutations exist.

Trait Implementations

impl<A: Adapter> Default for BatchTree<A>

fn default() -> Self

Returns the “default value” for a type.
