Struct ReprParser 

pub(crate) struct ReprParser;

Parse #[repr(…)] forms.

Valid repr contents: any of the primitive integral type names (see int_type_of_word, below) to specify enum discriminant type; C, to use the same discriminant size that the corresponding C enum would or C structure layout, packed to remove padding, and transparent to delegate representation concerns to the only non-ZST field.

Trait Implementations

impl<S: Stage> CombineAttributeParser<S> 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

type Item = (ReprAttr, Span)

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

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

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.
