Struct SeriesUpdatesRequest 

pub struct SeriesUpdatesRequest<'a> { /* private fields */ }

A builder for a series/updates request, returned by Client::series_updates. Lists the series updated most recently (ordered by last-updated time), optionally narrowed to a class of series. Finish with send.

use ferric_fred::UpdatesFilter;
let results = client
    .series_updates()
    .filter(UpdatesFilter::Macro)
    .limit(20)
    .send()
    .await?;
println!("{} series recently updated", results.count);

Implementations

impl<'a> SeriesUpdatesRequest<'a>

pub fn filter(self, filter: UpdatesFilter) -> Self

Narrow the results to a class of series (filter_value); defaults to all.

pub fn time_window(self, start: NaiveDateTime, end: NaiveDateTime) -> Self

Limit results to series updated within a time window (start_time / end_time), down to the minute. FRED requires these as a pair, so this method takes both bounds at once (ADR-0019).

The times are naive wall-clock in FRED’s own timezone — they are sent as given (formatted %Y%m%d%H%M), with no timezone conversion and minute granularity.

pub fn limit(self, limit: u32) -> Self

Maximum number of results to return, 1..=1000 (limit).

pub fn offset(self, offset: u32) -> Self

Number of results to skip from the start (offset), for paging.

pub async fn send(self) -> Result<SeriesSearchResults>

Run the request and return the recently-updated series with pagination metadata.

Errors

Returns an error if the request fails to send, FRED returns a non-success status, or the response body cannot be deserialized.

Trait Implementations

impl<'a> Clone for SeriesUpdatesRequest<'a>

fn clone(&self) -> SeriesUpdatesRequest<'a>

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<'a> Debug for SeriesUpdatesRequest<'a>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Paginate for SeriesUpdatesRequest<'_>

const MAX_PAGE: u32 = 1000

FRED’s maximum page size for this endpoint — the largest limit it honors. 1000 for most lists; 10000 for release dates and vintage dates.

type Page = SeriesSearchResults

The page type this request returns.

fn requested_limit(&self) -> Option<u32>

The caller’s requested limit, if set. send_all treats it as a ceiling on the total number of items returned.

fn requested_offset(&self) -> Option<u32>

The caller’s requested offset, if set — the point send_all starts paging from.

fn with_paging(self, limit: u32, offset: u32) -> Self

Return a copy of this request with limit and offset set.

fn send_page(self) -> impl Future<Output = Result<Self::Page>> + Send

Send a single page — equivalent to the builder’s own send.

fn send_all( self, ) -> impl Future<Output = Result<Vec<<Self::Page as Page>::Item>>> + Send

Fetch every result across all pages, in order.

fn stream(self) -> impl Stream<Item = Result<<Self::Page as Page>::Item>> + Send

Stream every result across all pages, lazily — items are yielded as they arrive, and the next page is fetched only once the current one is drained.
