Task Module

Namespace: TDesu.FSharp.Tasks
Assembly: TDesu.FSharp.dll

Task combinators — map, bind, zip, catch, and more for Task{T}.

All functions are inline for zero-overhead abstractions. Thread-safe by design.

Functions and values

Function or value	Description
`asUnit t` Full Usage: `asUnit t` Parameters: t : `Task` Returns: `Task<unit>` Modifiers: inline	Converts a non-generic Task to Task<unit>. The non-generic task to convert. t : `Task` Returns: `Task<unit>`
`bind f t` Full Usage: `bind f t` Parameters: f : `'T -> Task<'TResult>` t : `Task<'T>` Returns: `Task<'TResult>` Modifiers: inline Type parameters: 'T, 'TResult	Chains a task-returning function on the result of a task. The binding function returning a new task. The input task. f : `'T -> Task<'TResult>` t : `Task<'T>` Returns: `Task<'TResult>`
`catch t` Full Usage: `catch t` Parameters: t : `Task<'T>` - The task to execute inside a try/catch. Returns: `Task<Result<'T, exn>>` Modifiers: inline Type parameters: 'T	Runs a task inside a try/catch, returning `Ok` on success or `Error(exn)` on failure. t : `Task<'T>` The task to execute inside a try/catch. Returns: `Task<Result<'T, exn>>`
`fireAndForget onError f` Full Usage: `fireAndForget onError f` Parameters: onError : `exn -> unit` - Callback invoked with the exception if the task faults. f : `unit -> Task` - Factory that produces the task to run. Modifiers: inline	Fire-and-forget: starts a task without awaiting. Logs exceptions via onError. onError should not throw; if it does, the exception is silently swallowed. onError : `exn -> unit` Callback invoked with the exception if the task faults. f : `unit -> Task` Factory that produces the task to run.
`getResult t` Full Usage: `getResult t` Parameters: t : `Task<'a>` Returns: `'a` Modifiers: inline Type parameters: 'a	Synchronously gets the result of a Task (ConfigureAwait false). The task whose result to retrieve. t : `Task<'a>` Returns: `'a`
`ignore t` Full Usage: `ignore t` Parameters: t : `Task<'a>` Returns: `Task<unit>` Modifiers: inline Type parameters: 'a	Discards the task result, returning Task<unit>. The task whose result to discard. t : `Task<'a>` Returns: `Task<unit>`
`map f t` Full Usage: `map f t` Parameters: f : `'T -> 'TResult` t : `Task<'T>` Returns: `Task<'TResult>` Modifiers: inline Type parameters: 'T, 'TResult	Maps the result of a task with the given function. The mapping function. The input task. f : `'T -> 'TResult` t : `Task<'T>` Returns: `Task<'TResult>`
`map2 f t1 t2` Full Usage: `map2 f t1 t2` Parameters: f : `'T1 -> 'T2 -> 'TResult` t1 : `Task<'T1>` t2 : `Task<'T2>` Returns: `Task<'TResult>` Modifiers: inline Type parameters: 'T1, 'T2, 'TResult	Maps a function over two task results, running them concurrently. The mapping function taking two values. The first task. The second task. f : `'T1 -> 'T2 -> 'TResult` t1 : `Task<'T1>` t2 : `Task<'T2>` Returns: `Task<'TResult>`
`parallelThrottle maxConcurrent items f` Full Usage: `parallelThrottle maxConcurrent items f` Parameters: maxConcurrent : `int` - Maximum number of tasks allowed to run concurrently. items : `'T seq` - The input sequence of items to process. f : `'T -> Task<'TResult>` - Async function applied to each item. Returns: `Task<'TResult[]>`	Runs tasks in parallel with a throttle (max concurrent). Returns all results. On Fable, runs without throttling (JS is single-threaded). maxConcurrent : `int` Maximum number of tasks allowed to run concurrently. items : `'T seq` The input sequence of items to process. f : `'T -> Task<'TResult>` Async function applied to each item. Returns: `Task<'TResult[]>`
`parallelThrottleUnit maxConcurrent items f` Full Usage: `parallelThrottleUnit maxConcurrent items f` Parameters: maxConcurrent : `int` items : `'T seq` f : `'T -> Task<unit>` Returns: `Task<unit>`	Runs tasks in parallel with a throttle, ignoring results. Maximum number of tasks allowed to run concurrently. The input sequence of items to process. Async function applied to each item. maxConcurrent : `int` items : `'T seq` f : `'T -> Task<unit>` Returns: `Task<unit>`
`runSynchronously t` Full Usage: `runSynchronously t` Parameters: t : `'a`	Blocks until the task completes (ConfigureAwait false). No-op if null or already completed. The task to wait on. t : `'a`
`singleton v` Full Usage: `singleton v` Parameters: v : `'T` Returns: `Task<'T>` Modifiers: inline Type parameters: 'T	Wraps a value in a completed task. The value to wrap. v : `'T` Returns: `Task<'T>`
`waitUntil timeout condition` Full Usage: `waitUntil timeout condition` Parameters: timeout : `TimeSpan` - Maximum duration to wait. condition : `unit -> bool` - Predicate polled until it returns true. Returns: `Task<bool>`	Polls a condition with short delays until it returns true or timeout is reached. Returns true if condition was met, false on timeout. timeout : `TimeSpan` Maximum duration to wait. condition : `unit -> bool` Predicate polled until it returns true. Returns: `Task<bool>`
`zip t1 t2` Full Usage: `zip t1 t2` Parameters: t1 : `Task<'T1>` t2 : `Task<'T2>` Returns: `Task<'T1 * 'T2>` Modifiers: inline Type parameters: 'T1, 'T2	Combines two tasks into a tuple, running them concurrently. The first task. The second task. t1 : `Task<'T1>` t2 : `Task<'T2>` Returns: `Task<'T1 * 'T2>`
`zip3 t1 t2 t3` Full Usage: `zip3 t1 t2 t3` Parameters: t1 : `Task<'T1>` t2 : `Task<'T2>` t3 : `Task<'T3>` Returns: `Task<'T1 * 'T2 * 'T3>` Modifiers: inline Type parameters: 'T1, 'T2, 'T3	Combines three tasks into a triple, running them concurrently. The first task. The second task. The third task. t1 : `Task<'T1>` t2 : `Task<'T2>` t3 : `Task<'T3>` Returns: `Task<'T1 * 'T2 * 'T3>`
