Enum rustc_session::session::IncrCompSession

enum IncrCompSession {
    NotInitialized,
    Active {
        session_directory: PathBuf,
        _lock_file: Lock,
    },
    Finalized {
        session_directory: PathBuf,

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

Fields

session_directory: PathBuf

_lock_file: Lock

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

Fields

session_directory: PathBuf

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

Fields

session_directory: PathBuf

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.

Trait Implementations

impl Debug for IncrCompSession

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

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.
