use-dockerfile

Primitive Dockerfile instruction line helpers for RustUse.

This crate parses and renders single Dockerfile instruction lines. It does not try to evaluate Dockerfile semantics, handle line continuations, or build images.

Basic Usage

use use_dockerfile::{DockerfileInstruction, DockerfileInstructionKind};

let instruction: DockerfileInstruction = "FROM rust:1.95".parse()?;
let run = DockerfileInstruction::run("cargo test");

assert_eq!(instruction.kind(), DockerfileInstructionKind::From);
assert_eq!(run.to_string(), "RUN cargo test");
# Ok::<(), Box<dyn std::error::Error>>(())
