Type Definition oceanpkg::drop::license::spdx::Map

type Map<A> = [A; 374];

A fixed-size array for indexing with a SpdxLicense casted to usize. See also SpdxLicense::COUNT.

This is a good example of flexible management of SpdxLicense values that allows for indexing without bounds checks (via as usize casts) for free.

SemVer Compatibility: Like SpdxLicense::COUNT, by just being dependent on this value, the array size is allowed to change between otherwise API-compatible versions.

Examples

Despite array indexing having bounds checks, the optimizer knows that indexing with SpdxLicense will never go out of bounds, giving us simple and fast arithmetic for lookups.

use linfo::spdx::{Map, SpdxLicense};

let map: Map<&str> = [
    // *a lot* of elements per license
];

let license = SpdxLicense::Mit;
println!("map value is: {}", map[license as usize]);
