Enum IncrCompSession

Source 
enum IncrCompSession {
    NotInitialized,
    Active {
        session_directory: PathBuf,
        _lock_file: Lock,
    },
    Finalized {
        session_directory: PathBuf,
    },
    InvalidBecauseOfErrors {
        session_directory: PathBuf,
    },
}
Expand description

Holds data on the current incremental compilation session, if there is one.

Variants§

§

NotInitialized

This is the state the session will be in until the incr. comp. dir is needed.

§

Active

This is the state during which the session directory is private and can be modified. _lock_file is never directly used, but its presence alone has an effect, because the file will unlock when the session is dropped.

Fields

§session_directory: PathBuf
§_lock_file: Lock
§

Finalized

This is the state after the session directory has been finalized. In this state, the contents of the directory must not be modified any more.

Fields

§session_directory: PathBuf
§

InvalidBecauseOfErrors

This is an error state that is reached when some compilation error has occurred. It indicates that the contents of the session directory must not be used, since they might be invalid.

Fields

§session_directory: PathBuf
