Enum ValueSite 

pub enum ValueSite {
    Membership {
        array_items: Vec<usize>,
    },
    Cast(String),
    CompositeRow(CompositeRowBinding),
    Literal,
    Constant {
        value: Value,
        ty: String,
    },
    Relabel(String),
    FunctionOrder(FunctionOrderSyntax),
    Node,
}

An expression site of stored syntax and what binding recorded for it.

Variants

Membership

Positions grouped into a scalar-array comparison; the other IN items become individual comparisons.

Fields

array_items: Vec<usize>

Cast(String)

A cast, with the type name binding gave it.

CompositeRow(CompositeRowBinding)

A ROW constructor bound to its original composite attribute positions.

Literal

An unknown literal that binding left unconverted.

Constant

An unknown literal that binding converted to a typed constant.

Fields

value: Value

ty: String

Relabel(String)

A cast binding wrapped around the syntax, coercing an operand to the type its operator declares, as a RelabelType or an implicit coercion does.

FunctionOrder(FunctionOrderSyntax)

A function’s written ordering syntax, including a legacy call whose selected binding recovered the distinction.

Node

Any other node of stored syntax, which keeps the sites in step with the syntax so that a relabel reaches the node it wraps.
