Module config

Serialized configuration of a build.

This module implements parsing config.toml configuration files to tweak how the build runs.

Re-exports

pub use crate::core::config::flags::Subcommand;

Macros

check_ci_llvm 🔒

define_config 🔒

Structs

Build 🔒

TOML representation of various global build decisions.

ChangeIdWrapper 🔒

Since we use #[serde(deny_unknown_fields)] on TomlConfig, we need a wrapper type for the “change-id” field to parse it even if other fields are invalid. This ensures that if deserialization fails due to other fields, we can still provide the changelogs to allow developers to potentially find the reason for the failure in the logs..

Config

Global configuration for the entire build and/or bootstrap.

Dist 🔒

Gcc 🔒

TOML representation of how the GCC build is configured.

Install 🔒

TOML representation of various global install decisions.

Llvm 🔒

TOML representation of how the LLVM build is configured.

OptimizeVisitor 🔒

Rust 🔒

TOML representation of how the Rust build is configured.

Target

Per-target configuration stored in the global configuration structure.

TargetSelection

TargetSelectionList

Newtype over Vec<TargetSelection> so we can implement custom parsing logic

TomlConfig 🔒

Structure of the config.toml file that configuration is read from.

TomlTarget 🔒

TOML representation of how each build target is configured.

Enums

DebuginfoLevel

DryRun

GccCiMode

Determines how will GCC be provided.

LldMode

LLD in bootstrap works like this:

LlvmLibunwind

ReplaceOpt 🔒

Describes how to handle conflicts in merging two TomlConfig

RustOptimize

RustcLto

LTO mode used for compiling rustc itself.

RustfmtState

SplitDebuginfo

StringOrBool

StringOrInt 🔒

Constants

BUILDER_CONFIG_FILENAME 🔒

This file is embedded in the overlay directory of the tarball sources. It is useful in scenarios where developers want to see how the tarball sources were generated.

RUSTC_IF_UNCHANGED_ALLOWED_PATHS 🔒

Each path in this list is considered “allowed” in the download-rustc="if-unchanged" logic. This means they can be modified and changes to these paths should never trigger a compiler build when “if-unchanged” is set.

Traits

Merge 🔒

Functions

check_incompatible_options_for_ci_llvm 🔒

Compares the current Llvm options against those in the CI LLVM builder and detects any incompatible options. It does this by destructuring the Llvm instance to make sure every Llvm field is covered and not missing.

check_incompatible_options_for_ci_rustc 🔒

Compares the current Rust options against those in the CI rustc builder and detects any incompatible options. It does this by destructuring the Rust instance to make sure every Rust field is covered and not missing.

format_optimize_error_msg 🔒

target_selection_list
