Enum Container

pub enum Container<Q: QueryContext> {
    Variable(Variable),
    Accessor(Box<Accessor<Q>>),
    ListIndex(Box<ListIndex<Q>>),
    FunctionCall(Box<CallBuiltIn<Q>>),
}

A Container represents anything which “contains” a reference to a Pattern.

We have three types of containers:

• Variable: a variable reference (ex. $foo)
• Accessor: a map accessor (ex. $foo.bar)
• ListIndex: a list index (ex. $foo[0])

Variants

Variable(Variable)

Accessor(Box<Accessor<Q>>)

ListIndex(Box<ListIndex<Q>>)

FunctionCall(Box<CallBuiltIn<Q>>)

Implementations
