Enum VariantError

#[non_exhaustive]
pub enum VariantError {
    BadVariant(String),
    FileRead(String, String, Error),
    OsRelease(YAIError),
    UnknownVariant,
    Internal(String),
}

An error that occurred while determining the Linux variant.

Variants (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.

BadVariant(String)

An invalid variant name was specified.

FileRead(String, String, Error)

A file to be examined could not be read.

OsRelease(YAIError)

Unexpected error parsing the /etc/os-release file.

UnknownVariant

None of the variants matched.

Internal(String)

Something went really, really wrong.

Trait Implementations
