Enum CargoFreshError 

pub enum CargoFreshError {
    CargoListFailed {
        source: Error,
    },
}

用户运行 cargo-fresh 时能识别出的几类典型失败。

目前只覆盖会真正冒泡到 main 的路径——fetch_latest_versions 内部把 网络错误全部吞成空候选，所以 registry 相关的失败不会以错误形式出现。 网络层提示由 hint_for 中对 reqwest::Error 的直接匹配兜底，未来若 决定把 registry 错误外抛，可在此处增补变体。

Variants

CargoListFailed

cargo install --list 子进程跑失败：cargo 不在 PATH、cargo home 损坏等。

Fields

source: Error
