Crate rustc_attr_ir 

Data structures for representing parsed attributes in the Rust compiler.

For detailed documentation about attribute processing, see rustc_attr_parsing.

Re-exports

Modules

attr 🔒

canonical_symbols 🔒

data_structures 🔒

diagnostic

Contains the data structures used by the diagnostic attribute family.

diagnostic_items

encode_cross_crate 🔒

lang_items

Defines lang items.

pretty_printing 🔒

stability 🔒

target

This module lists attribute targets, with conversions from other types.

weak_lang_items

Validity checking for weak lang items

Macros

find_attr

Finds attributes in sequences of attributes by pattern matching.

Structs

AttrItem

AttrPath

AutoDiffItem

We generate one of these structs for each #[autodiff(...)] attribute.

CanonicalSymbol

A representation of a canonical symbol

CanonicalSymbols

CfgHideShow

ConstStability

Represents the #[rustc_const_unstable] and #[rustc_const_stable] attributes.

DebugVisualizer

DefaultBodyStability

Represents the #[rustc_default_body_unstable] attribute.

Deprecation

DocAttribute

DocCfgHideShowValue

EiiDecl

EiiImpl

HashIgnoredAttrId

The derived implementation of StableHash on Attributes shouldn’t hash AttrIds. By wrapping them in this, we make sure we never do.

LinkEntry

PartialConstStability

Excludes const_stable_indirect. This is necessary because when -Zforce-unstable-if-unmarked is set, we need to encode standalone #[rustc_const_stable_indirect] attributes

RustcAutodiff

RustcCleanAttribute

RustcCleanQueries

Represents the except= or loaded_from_disk= argument of #[rustc_clean]

RustcVersion

SanitizerSet

Stability

Represents the following attributes:

StrippedCfgItem

UnstableRemovedFeature

Enums

AttrArgs

Arguments passed to an attribute macro.

Attribute

Many functions on this type have their documentation in the AttributeExt trait, since they defer their implementation directly to that trait.

AttributeKind

Represents parsed built-in inert attributes.

BorrowckGraphvizFormatKind

CfgEntry

CguFields

CguKind

CollapseMacroDebuginfo

How to perform collapse macros debug info if-ext - if macro from different crate (related to callsite code) | cmd \ attr | no | (unspecified) | external | yes | | no | no | no | no | no | | (unspecified) | no | no | if-ext | yes | | external | no | if-ext | if-ext | yes | | yes | yes | yes | yes | yes |

CoverageAttrKind

Successfully-parsed value of a #[coverage(..)] attribute.

CrateType

Crate type, as specified by #![crate_type]

DebuggerVisualizerType

DeprecatedSince

Release in which an API is deprecated.

InlineAttr

InstructionSetAttr

InstrumentFnAttr

IntType

Linkage

Possible values for the #[linkage] attribute, allowing to specify the linkage type for a MonoItem.

MacroUseArgs

MirDialect

MirPhase

NativeLibKind

OptimizeAttr

PeImportNameType

Different ways that the PE Format can decorate a symbol name. From https://docs.microsoft.com/en-us/windows/win32/debug/pe-format#import-name-type

ReprAttr

RtsanSetting

RustcAbiAttrKind

Successfully-parsed value of a #[rustc_abi(..)] attribute.

RustcDumpLayoutKind

RustcMirKind

StabilityLevel

The available stability levels.

StableSince

Rust release in which a feature is stabilized.

TransparencyError

UnrollAttr

UnstableReason

UsedBy

There are three valid forms of the attribute: #[used], which is equivalent to #[used(linker)] on targets that support it, but #[used(compiler)] if not. #[used(compiler)] #[used(linker)]

WindowsSubsystemKind

Constants

VERSION_PLACEHOLDER

The version placeholder that recently stabilized features contain inside the since field of the #[stable] attribute.

Traits

HasAttrs

A trait for types that can provide a list of attributes given a TyCtxt.

PrintAttribute

This trait is used to print attributes in rustc_hir_pretty.
