Some facilities for tracking how codegen-units are reused during incremental compilation. This is used for incremental compilation tests and debug output.
Contains infrastructure for configuring the compiler, including parsing command-line options.
Related to out filenames of compilation (e.g. save analysis, binaries).
ParseSess which holds state living beyond what one
It also serves as an input to the parser itself.
Declares a static item of type
Declares a type named
$name which implements
To the right of
=> a comma separated list of
Lint statics is given.
LintPass for $ty with the given list of
Metadata associated with an item.
Hash value constructed out of all the
-C metadata arguments passed to the
compiler. Together with the crate-name forms a unique global identifier for
New-type wrapper around
usize for representing limits. Ensures that comparisons against
limits are consistent throughout the compiler.
Represents the data associated with a compilation session for a single crate.
The behavior of the CTFE engine when an error occurs with regards to backtraces.
Diagnostic message ID, used by
Session.one_time_diagnostics to avoid
emitting the same message more than once.
Holds data on the current incremental compilation session, if there is one.
Requirements for a
StableHashingContext to be used in this crate.
This is a hack to allow using the
HashStable_Generic derive macro
instead of implementing everything in
Trait implemented by error types. This should not be implemented manually. Instead, use
#[derive(SessionDiagnostic)] – see rustc_macros::SessionDiagnostic.
