Enum Designator 

pub enum Designator {
    Field(Symbol),
    Index(ExprId),
    Range {
        lo: ExprId,
        hi: ExprId,
    },
    ObsoleteField(Symbol),
}

One step of a designation, or of a __builtin_offsetof member path.

Variants

Field(Symbol)

.name.

Index(ExprId)

[index].

Range

[lo ... hi], GNU’s range, which initializes a run of elements with one value.

Fields

lo: ExprId

The first index.

hi: ExprId

The last index, which is included.

ObsoleteField(Symbol)

name:, the form GCC had before C99 and still accepts, with a warning under -pedantic. Kept apart from Designator::Field so the printer puts back what was written and so the diagnostic can point at the right thing.
