Structs

ConstStability

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

DefaultBodyStability

Represents the #[rustc_default_body_unstable] attribute.

Deprecation

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

RustcVersion

Stability

Represents the following attributes:

Enums

AttributeKind

Represents parsed built-in inert attributes.

DeprecatedSince

Release in which an API is deprecated.

InlineAttr

InstructionSetAttr

IntType

OptimizeAttr

ReprAttr

StabilityLevel

The available stability levels.

StableSince

Rust release in which a feature is stabilized.

TransparencyError

UnstableReason

Constants

VERSION_PLACEHOLDER

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

Traits

HashStableContext

Requirements for a StableHashingContext to be used in this crate. This is a hack to allow using the HashStable_Generic derive macro instead of implementing everything in rustc_middle.

PrintAttribute

This trait is used to print attributes in rustc_hir_pretty.
