all

Executes multiple tasks with concurrency and execution modes

Signature

all<T>(tasks, options?): Promise<TryoResult<T, E>[]>

Options

• Inherits all run options
• concurrency: maximum simultaneous tasks (default: unbounded)

Example

import { all, tryo } from 'tryo'

const tasks = [
  () => fetch('/a').then(r => r.text()),
  () => fetch('/b').then(r => r.text()),
]

const results = await all<string>(tasks, {
  concurrency: 2,
})

// Or using an instance
const ex = tryo()
const resultsInstance = await ex.all(tasks)
const { ok, failure } = ex.partitionAll(resultsInstance)

Result per Item

Each item in the returned array is a TryoResult:

• Success: { ok: true, data: T, error: null, metrics: TryoMetrics }
• Failure: { ok: false, data: null, error: TypedError, metrics: TryoMetrics }

The array always has the same length as the input tasks array. If a task wasn’t started due to an early abort, it will be returned as an ABORTED error result.
