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.

JsonConfig

Possible json config files

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

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

EntryFnType

ErrorOutputType

The type of diagnostics output to generate.

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.

How to run proc-macro code when building this crate

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.

TrimmedDefPaths

Parameter to control path trimming.

rustc_optgroups

Returns all rustc command line options, including metadata for each option, such as whether the option is part of the stable long-term interface for rustc.

rustc_short_optgroups

Returns the “short” subset of the rustc command line options, including metadata for each option, such as whether the option is part of the stable long-term interface for rustc.

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.
