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.
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.
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.

Layout§
Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...)
attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
