Module rustc_session::config[−][src]

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.

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.

BorrowckMode
CFGuard	The different settings that the `-C control-flow-guard` flag can have.
CrateType
DebugInfo
EntryFnType
ErrorOutputType	The type of diagnostics output to generate.
ExternDepSpec	Supplied source location of a dependency - for example in a build specification file like Cargo.toml. We support several syntaxes: if it makes sense to reference a file and line, then the build system can specify that. On the other hand, it may make more sense to have an arbitrary raw string.

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.

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_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.
