Overview ¶

Package parallel provides utilities for parallel execution of operations.

Index ¶

Constants
func ExecuteMap[K comparable, V any, R any](ctx context.Context, entries map[K]V, ...) map[K]*Result[R]
func ExecuteMapWithLimit[K comparable, V any, R any](ctx context.Context, entries map[K]V, limit int, ...) map[K]*Result[R]
type Result

const DefaultLimit = 10

DefaultLimit is the default concurrency limit for parallel operations.

Functions ¶

func ExecuteMap ¶

func ExecuteMap[K comparable, V any, R any](
	ctx context.Context,
	entries map[K]V,
	fn func(ctx context.Context, key K, value V) (R, error),
) map[K]*Result[R]

ExecuteMap runs fn for each key-value pair in entries concurrently. Results are collected in a map keyed by the same keys as entries. Individual errors are captured in Result.Err rather than failing the entire operation.

func ExecuteMapWithLimit ¶

func ExecuteMapWithLimit[K comparable, V any, R any](
	ctx context.Context,
	entries map[K]V,
	limit int,
	fn func(ctx context.Context, key K, value V) (R, error),
) map[K]*Result[R]

ExecuteMapWithLimit is like ExecuteMap but with a custom concurrency limit.

Types ¶

type Result ¶

type Result[T any] struct {
	Value T
	Err   error
}

Result holds the result of a parallel operation.
