Enum Discriminator 

pub enum Discriminator {
    Known(Int),
    Invalid,
    Branch {
        offset: Size,
        value_type: IntType,
        fallback: GcCow<Discriminator>,
        children: Map<(Int, Int), Discriminator>,
    },
}

The decision tree that computes the discriminant out of the tag for a specific enum type.

Variants

Known(Int)

We know the discriminant.

Invalid

Tag decoding failed, there is no valid discriminant.

Branch

We don’t know the discriminant, so we branch on the value of a specific value.

Fields

offset: Size

value_type: IntType

fallback: GcCow<Discriminator>

children: Map<(Int, Int), Discriminator>

An left-inclusive right-exclusive range of values that map to some Discriminator.
