Variants (Non-exhaustive)

This enum is marked as non-exhaustive

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

`ChannelNotAvailable(Channel)`

Returned when the channel is not available, that is, is unimplemented.

`DeserializeToml(Error)`

Returned when a retrieved manifest is not decodable as TOML.

`ParseManifestDate`

Returned when the manifest date can not be parsed.

`ParseManifestSource`

Returned when the manifest source can not be parsed from the top level meta manifest.

`ParseMetaManifest`

Returned when the top level meta manifest can not be parsed.

`ParseRustVersion(Error)`

Returned when there is an issue with a semver version.

`RustReleasesIoError(IoError)`

Returned in case of an I/O error.

`RustVersionNotFoundInManifest`

Returned when the Rust version can not be found in a release manifest.
