Module rustc_session::config

Contains infrastructure for configuring the compiler, including parsing command-line options.

Modules

• dep_tracking 🔒
  Command-line arguments passed to the compiler have to be incorporated with the dependency tracking system for incremental compilation. This module provides some utilities to make this more convenient.
• nightly_options
• opt 🔒
• sigpipe
  NOTE: Keep these constants in sync with library/std/src/sys/unix/mod.rs!

Structs

• BranchProtection
• CheckCfg
  The parsed --check-cfg options
• CodegenOptions
• ExternEntry
• Externs
  Use tree-based collections to cheaply get a deterministic Hash implementation. Do not switch BTreeMap or BTreeSet out for an unsorted container type! That would break dependency tracking for command-line arguments.
• InstrumentXRay
  Settings for -Z instrument-xray flag.
• JsonConfig
  Possible json config files
• LinkSelfContained
  The different values -C link-self-contained can take: a list of individually enabled or disabled components used during linking, coming from the rustc distribution, instead of being found somewhere on the host system.
• LinkSelfContainedComponents
  The -C link-self-contained components that can individually be enabled or disabled.
• LocationDetail
  The different settings that can be enabled via the -Z location-detail flag.
• Options
  The top-level command-line options struct.
• OutputFilenames
• OutputTypes
  Use tree-based collections to cheaply get a deterministic Hash implementation. Do not switch BTreeMap out for an unsorted container type! That would break dependency tracking for command-line arguments. Also only hash keys, since tracking should only depend on the output types, not the paths they’re written to.
• PacRet
• PrintRequest
• RustcOptGroup
• UnstableOptions

Enums

• CFGuard
  The different settings that the -C control-flow-guard flag can have.
• CFProtection
  The different settings that the -Z cf-protection flag can have.
• CrateType
• DebugInfo
• DebugInfoCompression
• DumpMonoStatsFormat
  Which format to use for -Z dump-mono-stats
• DumpSolverProofTree
• EntryFnType
• ErrorOutputType
  The type of diagnostics output to generate.
• ExpectedValues
• ExternLocation
• IncrementalStateAssertion
  Used with -Z assert-incr-state.
• Input
• InstrumentCoverage
  The different settings that the -C instrument-coverage flag can have.
• JsonUnusedExterns
  Report unused externs in event stream
• LdImpl
• LinkerPluginLto
• Lto
  This is what the LtoCli values get mapped to after resolving defaults and and taking other command line options into account.
• LtoCli
  The different settings that the -C lto flag can have.
• MirSpanview
  The different settings that the -Z dump_mir_spanview flag can have. Statement generates a document highlighting each span of every statement (including terminators). Terminator and Block highlight a single span per BasicBlock: the span of the block’s Terminator, or a computed span for the block, representing the entire range, covering the block’s terminator and all of its statements.
• OomStrategy
  Default behavior to use in out-of-memory situations.
• OptLevel
• OptionStability
• OutFileName
• OutputType
• PAuthKey
• Passes
• PpAstTreeMode
• PpHirMode
• PpMode
• PpSourceMode
• PrintKind
• ProcMacroExecutionStrategy
  How to run proc-macro code when building this crate
• ResolveDocLinks
• SplitDwarfKind
  Split debug-information is enabled by -C split-debuginfo, this enum is only used if split debug-information is enabled (in either Packed or Unpacked modes), and the platform uses DWARF for debug-information.
• Strip
  The different settings that the -C strip flag can have.
• SwitchWithOptPath
• SymbolManglingVersion
• TraitSolver
• TrimmedDefPaths
  Parameter to control path trimming.
• WasiExecModel

• to_crate_check_config
  Converts the crate --check-cfg options from String to Symbol. rustc_interface::interface::Config accepts this in the compiler configuration, but the symbol interner is not yet set up then, so we must convert it later.
• to_crate_config
  Converts the crate cfg! configuration from String to Symbol. rustc_interface::interface::Config accepts this in the compiler configuration, but the symbol interner is not yet set up then, so we must convert it later.
