Kind of an error returned from Client::from_env_ext function.

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.

NoEnvVar

There is no environment variable that describes jobserver to inherit.

NoJobserver

There is no jobserver in the environment variable. Variables associated with Make can be used for passing data other than jobserver info.

CannotParse

Cannot parse jobserver environment variable value, incorrect format.

CannotOpenPath

Cannot open path or name from the jobserver environment variable value.

CannotOpenFd

Cannot open file descriptor from the jobserver environment variable value.

NegativeFd

The jobserver style is a simple pipe, but at least one of the file descriptors is negative, which means it is disabled for this process (GNU make manual: POSIX Jobserver Interaction).

NotAPipe

File descriptor from the jobserver environment variable value is not a pipe.

Unsupported

Jobserver inheritance is not supported on this platform.
