dnf-repofile 0.1.2

//! Builder-pattern API for constructing [`Repo`] values.
//!
//! [`RepoBuilder`] provides a fluent interface for programmatic creation of
//! repository configurations without manually setting each field on a
//! [`Repo`] struct.
//!
//! # Examples
//!
//! ```
//! use dnf_repofile::{RepoBuilder, RepoId, RepoName, DnfBool, Priority};
//!
//! let repo = RepoBuilder::new(RepoId::try_new("custom").unwrap())
//!     .name(RepoName::try_new("Custom Repository").unwrap())
//!     .baseurl("https://example.com/".parse().unwrap())
//!     .enabled(DnfBool::yes())
//!     .gpgcheck(DnfBool::yes())
//!     .priority(Priority::try_new(50).unwrap())
//!     .build();
//!
//! assert_eq!(repo.name.as_ref().unwrap().as_ref(), "Custom Repository");
//! ```
