Error enum for the entire crate.

Variants

ParseVersionComponentError(ParseIntError)

String passed to RequestedVersion::from_str or ExactVersion::from_str has an expected digit component that cannot be parsed as an integer.

DotMissing

ExactVersion::from_str is passed a string missing a ..

FileNameMissing

ExactVersion::from_path is given a Path which lacks a file name.

FileNameToStrError

PathFileNameError

An unexpected file name was given to ExactVersion::from_path.

NoExecutableFound(RequestedVersion)
