Generator

dev_ci

Struct Generator 

Source 
pub struct Generator { /* private fields */ }
Expand description

Builder for a CI workflow document.

Methods are pure setters; configuration is committed only when generate is called. Calling generate multiple times against the same Generator returns byte-identical output.

§Example

use dev_ci::{Generator, PathDep, Target};

let yaml = Generator::new()
    .target(Target::GitHubActions)
    .workflow_name("CI")
    .branches(["main", "release/*"])
    .matrix_os(["ubuntu-latest", "macos-latest", "windows-latest"])
    .with_clippy()
    .with_fmt()
    .with_docs()
    .with_msrv("1.85")
    .with_no_default_features_build()
    .with_all_features_build()
    .with_path_dep(PathDep::new("dev-report", "https://github.com/jamesgober/dev-report.git"))
    .generate();

assert!(yaml.contains("name: CI"));
assert!(yaml.contains("actions/checkout@v5"));

Implementations§

impl Generator

Source

pub fn new() -> Self

Begin a new generator with default settings.

Defaults: target = GitHubActions, workflow name = "CI", branches = ["main"], matrix = ["ubuntu-latest"], cache enabled, no extra jobs.

pub fn features(self, features: impl Into<String>) -> Self

Pass --features <list> to every cargo invocation.

Mutually exclusive with with_all_features_build only in the sense that --all-features overrides --features in cargo itself; the generator emits both flags as configured.

Source

pub fn with_no_default_features_build(self) -> Self

Emit an additional build step under the test job that passes --no-default-features. Useful for crates with optional features that should compile cleanly under the bare configuration.

pub fn with_path_dep(self, dep: PathDep) -> Self

Declare a sibling path-dependency that the workflow must git clone into ../<name> before running cargo.

Matches the pattern the existing dev-* suite uses for its own CI (each crate clones its siblings into ..). May be called repeatedly.
