<A>(element: A): (self: TxChunk<A>) => Effect.Effect<void>
<A>(self: TxChunk<A>, element: A): Effect.Effect<void>Appends an element to the end of the TxChunk.
Details
This function mutates the original TxChunk by adding the element to the end. It does not return a new TxChunk reference.
Example (Appending an element)
import { Chunk, Effect, TxChunk } from "effect"
const program = Effect.gen(function*() {
const txChunk = yield* TxChunk.fromIterable([1, 2, 3])
// Add element to the end atomically
yield* TxChunk.append(txChunk, 4)
const result = yield* TxChunk.get(txChunk)
console.log(Chunk.toReadonlyArray(result)) // [1, 2, 3, 4]
})combinators

interface TxChunk<in out A>TxChunk is a transactional chunk data structure that provides Software Transactional Memory (STM)
semantics for chunk operations.
Details
Accessed values are tracked by the transaction in order to detect conflicts and to track changes.
A transaction will retry whenever a conflict is detected or whenever the transaction explicitly
calls Effect.txRetry and any of the accessed TxChunk values change.
Example (Using a transactional chunk)
import { Chunk, Effect, TxChunk } from "effect"
const program = Effect.gen(function*() {
// Create a transactional chunk
const txChunk: TxChunk.TxChunk<number> = yield* TxChunk.fromIterable([
1,
2,
3
])
// Single operations - no explicit transaction needed
yield* TxChunk.append(txChunk, 4)
const result = yield* TxChunk.get(txChunk)
console.log(Chunk.toReadonlyArray(result)) // [1, 2, 3, 4]
// Multi-step atomic operation - use explicit transaction
yield* Effect.tx(
Effect.gen(function*() {
yield* TxChunk.prepend(txChunk, 0)
yield* TxChunk.append(txChunk, 5)
})
)
const finalResult = yield* TxChunk.get(txChunk)
console.log(Chunk.toReadonlyArray(finalResult)) // [0, 1, 2, 3, 4, 5]
