Enum `VarError`

enum VarError

The error type for operations interacting with environment variables. Possibly returned from env::var().

Variants

NotPresent: The specified environment variable was not present in the current process's environment.
NotUnicode(crate::ffi::OsString): The specified environment variable was found, but it did not contain valid unicode data. The found data is returned as a payload of this variant.
