Struct NoMatchDetails 

pub struct NoMatchDetails {
    pub name: String,
    pub range: String,
    pub importer: String,
    pub ancestors: Vec<(String, String)>,
    pub original_spec: Option<String>,
    pub available: Vec<String>,
    pub total_versions: usize,
    pub only_prereleases: bool,
}

Context attached to a NoMatch error so the miette help() output can show importer path, parent chain, and what versions the packument actually contains. Boxed into the enum variant to keep Error’s size under clippy::result_large_err.

Fields

name: String

range: String

importer: String

ancestors: Vec<(String, String)>

original_spec: Option<String>

available: Vec<String>

Up to 5 most-recent version strings from the packument. Stable versions are preferred; when the packument contains only prereleases we fall back to showing those so the diagnostic doesn’t misreport the packument as empty.

total_versions: usize

Total number of versions in the packument, including prereleases and unparseable keys. Used by the help text to distinguish a genuinely empty packument (wrong registry, missing package) from one that only publishes prereleases.

only_prereleases: bool

True when every shown entry in available is a prerelease — the user asked for a stable range but the registry only has alpha / beta / rc builds. Help text steers them toward name@next or a prerelease range.
