Struct libcnb_data::buildpack::MetaBuildpackDescriptor

pub struct MetaBuildpackDescriptor<BM> {
    pub api: BuildpackApi,
    pub buildpack: Buildpack,
    pub order: Vec<Order>,
    pub metadata: BM,
}

Data structure for the Buildpack descriptor (buildpack.toml) of a meta-buildpack.

Representation of buildpack.toml when the buildpack is a meta-buildpack.

If support for multiple buildpack types is required, use BuildpackDescriptor instead.

Example:

use libcnb_data::buildpack_id;
use libcnb_data::buildpack::MetaBuildpackDescriptor;

let toml_str = r#"
api = "0.8"

[buildpack]
id = "foo/bar"
name = "Bar Buildpack"
version = "0.0.1"
homepage = "https://www.foo.com/bar"
clear-env = false
description = "A buildpack for Foo Bar"
keywords = ["foo"]

[[buildpack.licenses]]
type = "BSD-3-Clause"

[[order]]

[[order.group]]
id = "foo/baz"
version = "0.0.1"
"#;

let buildpack_descriptor = toml::from_str::<MetaBuildpackDescriptor<Option<toml::value::Table>>>(toml_str).unwrap();
assert_eq!(buildpack_descriptor.buildpack.id, buildpack_id!("foo/bar"));
