Expand description

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

Modules

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.

Structs

The parsed --check-cfg options

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.

Possible json config files

The different settings that can be enabled via the -Z location-detail flag.

The top-level command-line options struct.

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.

Enums

The different settings that the -C control-flow-guard flag can have.

The different settings that the -Z cf-protection flag can have.

The type of diagnostics output to generate.

Used with -Z assert-incr-state.

The different settings that the -C instrument-coverage flag can have.

Report unused externs in event stream

This is what the LtoCli values get mapped to after resolving defaults and and taking other command line options into account.

The different settings that the -C lto flag can have.

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.

Default behavior to use in out-of-memory situations.

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.

The different settings that the -C strip flag can have.

Parameter to control path trimming.

Constants

Functions

Parses the --color flag.

Parses the --error-format flag.

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.

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.

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.

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.
