Trait libcnb::Platform

pub trait Platformwhere
    Self: Sized,{
    // Required methods
    fn env(&self) -> &Env;
    fn from_path(platform_dir: impl AsRef<Path>) -> Result<Self>;
}

Represents a Cloud Native Buildpack platform.

Most buildpacks target a generic platform and this library provides a crate::generic::GenericPlatform for that use-case. Buildpack authors usually do not need to implement this trait. See detection and build in the buildpack specification for details.

Required Methods

fn env(&self) -> &Env

Retrieve a Env reference for convenient access to environment variables which all platforms have to provide.

fn from_path(platform_dir: impl AsRef<Path>) -> Result<Self>

Initializes the platform from the given platform directory.

Examples

use libcnb::Platform;
use libcnb::generic::GenericPlatform;
let platform = GenericPlatform::from_path("/platform").unwrap();
