Struct ReprParser 

pub(crate) struct ReprParser;

Parse #[repr(…)] forms.

Valid repr contents:

• any of the primitive integral type names to specify enum discriminant type
• Rust, to use the default Rust layout of the type
• C, to use the same layout for the type that C would use
• align(...), to change the alignment requirements of the type
• packed, to remove padding
• transparent, to delegate representation concerns to the only non-ZST field.

Trait Implementations

impl CombineAttributeParser for ReprParser

const PATH: &[Symbol]

const CONVERT: fn(ThinVec<Self::Item>, Span) -> AttributeKind

A function that converts individual items (of type Item) into the final attribute.

const TEMPLATE: AttributeTemplate

The template this attribute parser should implement. Used for diagnostics.

const ALLOWED_TARGETS: AllowedTargets = AllowedTargets::ManuallyChecked

const STABILITY: AttributeStability = AttributeStability::Stable

type Item = (ReprAttr, Span)

fn extend( cx: &mut AcceptContext<'_, '_>, args: &ArgParser, ) -> impl IntoIterator<Item = Self::Item>

Converts a single syntactical attribute to a number of elements of the semantic attribute, or AttributeKind

const SAFETY: AttributeSafety = AttributeSafety::Normal

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
