guppy-summaries

提供序列化、反序列化和比较构建摘要的功能。

构建摘要是一个记录在目标平台和主机平台上构建了哪些包和特性的记录。摘要文件可以提交到仓库中，保持最新状态并在 CI 中进行比较，从而可以跟踪构建结果随时间的变化。

guppy-summaries 被设计得小巧且独立于主要的 guppy crate。

示例

use guppy_summaries::{Summary, SummaryId, SummarySource, PackageStatus};
use pretty_assertions::assert_eq;
use semver::Version;
use std::collections::BTreeSet;
use toml::Value;

// A summary is a TOML file that has this format:
static SUMMARY: &str = r#"

features = ["feature-a", "feature-c"]

[[host-package]]

features = ["macro-expand"]

[[host-package]]
name = "bar"
version = "0.4.5"
crates-io = true
status = 'direct'
features = []
"#;

// The summary can be deserialized:
let summary = Summary::parse(SUMMARY).expect("from_str succeeded");

// ... and a package and its features can be looked up.
let summary_id = SummaryId::new("foo", Version::new(1, 2, 3), SummarySource::workspace("foo"));

// Another summary.
