Trait SelfHref 

pub trait SelfHref {
    // Required methods
    fn self_href(&self) -> Option<&Href>;
    fn self_href_mut(&mut self) -> &mut Option<Href>;
}

Implemented by all three STAC objects, the SelfHref trait allows getting and setting an object’s href.

Though the self href isn’t part of the data structure, it is useful to know where a given STAC object was read from. Objects created from scratch don’t have an href.

Examples

use stac::{Item, SelfHref};

let item = Item::new("an-id");
assert!(item.self_href().is_none());
let item: Item = stac::read("examples/simple-item.json").unwrap();
assert!(item.self_href().is_some());

Required Methods

fn self_href(&self) -> Option<&Href>

Gets this object’s href.

Examples

use stac::{SelfHref, Item};

let item: Item = stac::read("examples/simple-item.json").unwrap();
assert!(item.self_href().unwrap().to_string().ends_with("simple-item.json"));

fn self_href_mut(&mut self) -> &mut Option<Href>

Returns a mutable reference to this object’s self href.

Examples

use stac::{Item, SelfHref};

let mut item = Item::new("an-id");
*item.self_href_mut() = Option::Some("./a/relative/path.json".into());
