Trait Extension

pub trait Extension: Serialize + DeserializeOwned {
    const IDENTIFIER: &'static str;
    const PREFIX: &'static str;

    // Provided method
    fn identifier_prefix() -> &'static str { ... }
}

A trait implemented by extensions.

So far, all extensions are assumed to live in under https://stac-extensions.github.io domain.

Required Associated Constants

const IDENTIFIER: &'static str

The schema URI.

const PREFIX: &'static str

The fiend name prefix.

Provided Methods

fn identifier_prefix() -> &'static str

Returns everything from the identifier up until the version.

Examples

use stac_extensions::{Raster, Extension};
assert_eq!(Raster::identifier_prefix(), "https://stac-extensions.github.io/raster/");

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
