bridge-option

{/* @generated by scripts/sync-content.mjs; do not edit */}

@sandlada/result/bridge-option — lifts a sync IOption<T> into Promise<IOption<…>> using async callbacks. Input is always a plain Option; output is always a Promise of Option. Same export names as option/map, but a different subpath and carrier type.

Scope

Section titled “Scope”
  • Operates on: synchronous IOption<T>; callbacks return Promise<…>.
  • Execution model: eager — calling the operator starts the returned Promise immediately.
  • Not here: eager pipelines over a resolved Option promise (promise-option), lazy thunks (async-option), or sync operators (option).

API

Section titled “API”
Export Description Source
map Async map on a sync Option. map.ts
bind Async bind on a sync Option. bind.ts
match Async terminal match on a sync Option. match.ts
orElse Async fallback on a sync Option. orElse.ts
tap Async side effect when Some. tap.ts

Contract notes

Section titled “Contract notes”
  • Promotion family: a synchronous throw becomes None; an async rejection propagates. See behavior-modes.md §4.6.1.
  • match propagates handler throws like promise-option/matchAsyncOption.
Section titled “Related”
  • promise-option — eager operators on a Promise of Option.
  • option — sync operators on plain Option values.
