ScopesTreeView
public struct ScopesTreeView
A view on the scopes tree defined by row adapters.
For example:
// Define a tree of nested scopes
let adapter = ScopeAdapter([
"foo": RangeRowAdapter(0..<1),
"bar": RangeRowAdapter(1..<2).addingScopes([
"baz" : RangeRowAdapter(2..<3)])])
// Fetch
let sql = "SELECT 1 AS foo, 2 AS bar, 3 AS baz"
let row = try Row.fetchOne(db, sql, adapter: adapter)!
row.scopesTree.names // ["foo", "bar", "baz"]
row.scopesTree["foo"] // [foo:1]
row.scopesTree["bar"] // [bar:2]
row.scopesTree["baz"] // [baz:3]
-
The scopes defined on this row, recursively.
