Struct FinalizeContext

pub(crate) struct FinalizeContext<'a> {
    pub(crate) cx: &'a AttributeParser<'a>,
    pub(crate) target_span: Span,
}

Context given to every attribute parser during finalization.

Gives AttributeParsers enough information to create errors, for example.

Fields

cx: &'a AttributeParser<'a>

The parse context, gives access to the session and the diagnostics context.

target_span: Span

The span of the syntactical component this attribute was applied to

Methods from Deref<Target = AttributeParser<'a>>

pub(crate) fn sess(&self) -> &'sess Session

pub(crate) fn features(&self) -> &'sess Features

pub(crate) fn dcx(&self) -> DiagCtxtHandle<'sess>

pub fn parse_attribute_list<'a>( &'a self, attrs: &'a [Attribute], target_span: Span, omit_doc: OmitDoc, lower_span: impl Copy + Fn(Span) -> Span, ) -> Vec<Attribute>

Parse a list of attributes.

target_span is the span of the thing this list of attributes is applied to, and when omit_doc is set, doc attributes are filtered out.

fn lower_attr_args( &self, args: &AttrArgs, lower_span: impl Fn(Span) -> Span, ) -> AttrArgs

Trait Implementations

impl<'a> Deref for FinalizeContext<'a>

type Target = AttributeParser<'a>

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.

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.
