Struct SyntaxContextData 

Source 
struct SyntaxContextData {
    outer_expn: ExpnId,
    outer_transparency: Transparency,
    parent: SyntaxContext,
    opaque: SyntaxContext,
    opaque_and_semiopaque: SyntaxContext,
    dollar_crate_name: Symbol,
}

Fields§

§outer_expn: ExpnId

The last macro expansion in the chain. (Here we say the most deeply nested macro expansion is the “outermost” expansion.)

§outer_transparency: Transparency

Transparency of the last macro expansion

§parent: SyntaxContext§opaque: SyntaxContext

This context, but with all transparent and semi-opaque expansions filtered away.

§opaque_and_semiopaque: SyntaxContext

This context, but with all transparent expansions filtered away.

§dollar_crate_name: Symbol

Name of the crate to which $crate with this context would resolve.
