Parameters for the items endpoint from STAC API - Features.

Fields

limit: Option<u64>

The maximum number of results to return (page size).

bbox: Option<Bbox>

Requested bounding box.

datetime: Option<String>

Single date+time, or a range (‘/’ separator), formatted to RFC 3339, section 5.6.

Use double dots .. for open date ranges.

fields: Option<Fields>

Include/exclude fields from item collections.

sortby: Vec<Sortby>

Fields by which to sort results.

filter_crs: Option<String>

Recommended to not be passed, but server must only accept http://www.opengis.net/def/crs/OGC/1.3/CRS84 as a valid value, may reject any others

filter: Option<Filter>

CQL2 filter expression.

query: Option<Map<String, Value>>

Additional filtering based on properties.

It is recommended to use the filter extension instead.

additional_fields: Map<String, Value>

Additional fields.

Implementations

impl Items

pub fn valid(self) -> Result<Items>

Runs a set of validity checks on this query and returns an error if it is invalid.

Returns the items, unchanged, if it is valid.

Examples

use stac::api::Items;

let items = Items::default().valid().unwrap();

pub fn matches(&self, item: &Item) -> Result<bool>

Returns true if this items structure matches the given item.

Examples

use stac::api::Items;
use stac::Item;

assert!(Items::default().matches(&Item::new("an-id")).unwrap());

pub fn bbox_matches(&self, item: &Item) -> Result<bool>

Returns true if this item’s geometry matches this search’s bbox.

If stac is not built with the geo feature, this will return an error.

Examples

use stac::api::Search;
use stac::Item;
use geojson::{Geometry, Value};

let mut search = Search::new();
let mut item = Item::new("item-id");
assert!(search.bbox_matches(&item).unwrap());
search.bbox = Some(vec![-110.0, 40.0, -100.0, 50.0].try_into().unwrap());
assert!(!search.bbox_matches(&item).unwrap());
item.set_geometry(Geometry::new_point(vec![-105.1, 41.1]));
assert!(search.bbox_matches(&item).unwrap());

pub fn datetime_matches(&self, item: &Item) -> Result<bool>

Returns true if this item’s datetime matches this items structure.

Examples

use stac::api::Search;
use stac::Item;

let mut search = Search::new();
let mut item = Item::new("item-id");  // default datetime is now
assert!(search.datetime_matches(&item).unwrap());
search.datetime = Some("../2023-10-09T00:00:00Z".to_string());
assert!(!search.datetime_matches(&item).unwrap());
item.properties.datetime = Some("2023-10-08T00:00:00Z".parse().unwrap());
assert!(search.datetime_matches(&item).unwrap());

pub fn query_matches(&self, _: &Item) -> Result<bool>

Returns true if this item’s matches this search query.

Currently unsupported, always raises an error if query is set.

Examples

use stac::api::Search;
use stac::Item;

let mut search = Search::new();
let mut item = Item::new("item-id");
assert!(search.query_matches(&item).unwrap());
search.query = Some(Default::default());
assert!(search.query_matches(&item).is_err());

pub fn filter_matches(&self, _: &Item) -> Result<bool>

Returns true if this item matches this search’s filter.

Currently unsupported, always raises an error if filter is set.

Examples

use stac::api::Search;
use stac::Item;

let mut search = Search::new();
let mut item = Item::new("item-id");
assert!(search.filter_matches(&item).unwrap());
search.filter = Some(Default::default());
assert!(search.filter_matches(&item).is_err());

pub fn search_collection(self, collection_id: impl ToString) -> Search

Converts this items object to a search in the given collection.

Examples

use stac::api::Items;
let items = Items {
    datetime: Some("2023".to_string()),
    ..Default::default()
};
let search = items.search_collection("collection-id");
assert_eq!(search.collections, vec!["collection-id"]);

pub fn into_cql2_json(self) -> Result<Items>

Converts the filter to cql2-json, if it is set.
