Macro buildpack_main

macro_rules! buildpack_main {
    ($buildpack:expr) => { ... };
}

Generates a main function for the given buildpack.

It will create the main function and wires up the buildpack to the framework.

Example:

use libcnb::build::{BuildContext, BuildResult, BuildResultBuilder};
use libcnb::detect::{DetectContext, DetectResult, DetectResultBuilder};
use libcnb::generic::{GenericError, GenericMetadata, GenericPlatform};
use libcnb::{buildpack_main, Buildpack};

pub(crate) struct MyBuildpack;

impl Buildpack for MyBuildpack {
    type Platform = GenericPlatform;
    type Metadata = GenericMetadata;
    type Error = GenericError;

    fn detect(
        &self,
        context: DetectContext<Self>,
    ) -> libcnb::Result<DetectResult, Self::Error> {
        DetectResultBuilder::pass().build()
    }

    fn build(&self, context: BuildContext<Self>) -> libcnb::Result<BuildResult, Self::Error> {
        BuildResultBuilder::new().build()
    }
}

buildpack_main!(MyBuildpack);
