示例1: action
export function withFileInfoCache<A>(
delay: number,
action: (getInfo: (hash: number) => (path: string) => T.Task<FileInfo>) => T.Task<A>
): T.Task<A> {
return delay === 0
? action(constant(getFileInfo))
: T.bracket(initialize(delay), terminate, s => action(getAndRegisterInfo(s)));
}示例2: action
export function withFdCache<A>(duration: number, action: (_: GetFd) => T.Task<A>): T.Task<A> {
return duration === 0
? action(P.constant(getFdNothing))
: T.bracket(initialize(duration), terminate, mfc => action(getFd(mfc)));
}示例3: it
it('#searchWith return Just if the key present and satisfy pred', function () {
const mmap = MM.singleton(10, 'ten');
assert.ok(P.isJust(MM.searchWith(10, P.constant(true), mmap)));
