Enum Binding 

pub enum Binding {
    Leaf(Expr),
    Group(GroupPlan),
    Inherit {
        from: Option<Expr>,
    },
}

A binding after normalization.

Variants

Leaf(Expr)

A value that is NOT a syntactic attrset literal, so it can never merge.

Group(GroupPlan)

A syntactic attrset literal, or an implicit one created by a dotted path. Mergeable — and merging splices into THIS node.

Inherit

inherit x / inherit (e) x. Never mergeable in either direction, so it is its own arm rather than a Leaf: an inherited binding colliding with anything is a reject, in both orders.

Fields

from: Option<Expr>

Some(e) for inherit (e) x; None for plain inherit x.

Trait Implementations
