View Source EdgeDB.NamedTuple (EdgeDB v0.7.0)

An immutable value representing an EdgeDB named tuple value.

EdgeDB.NamedTuple implements Access behavior to access fields by index or key and Enumerable protocol for iterating over tuple values.

iex(1)> {:ok, client} = EdgeDB.start_link()
iex(2)> nt = EdgeDB.query_required_single!(client, "select (a := 1, b := 'a', c := [3])")
#EdgeDB.NamedTuple<a: 1, b: "a", c: [3]>
iex(3)> nt[:b]
"a"
iex(4)> nt["c"]
[3]
iex(4)> nt[0]
1

Types

t()

@opaque t()

An immutable value representing an EdgeDB named tuple value.

Functions

keys(named_tuple)

@spec keys(t()) :: [String.t()]

Get named tuple keys.

iex(1)> {:ok, client} = EdgeDB.start_link()
iex(2)> nt = EdgeDB.query_required_single!(client, "select (a := 1, b := 'a', c := [3])")
iex(3)> EdgeDB.NamedTuple.keys(nt)
["a", "b", "c"]

to_map(named_tuple)

(since 0.3.0)

@spec to_map(t()) :: %{required(String.t()) => term()}

Convert a named tuple into a regular map.

iex(1)> {:ok, client} = EdgeDB.start_link()
iex(2)> nt = EdgeDB.query_required_single!(client, "select (a := 1, b := 'a', c := [3])")
iex(3)> EdgeDB.NamedTuple.to_map(nt)
%{"a" => 1, "b" => "a", "c" => [3]}

to_tuple(nt)

@spec to_tuple(t()) :: tuple()

Convert a named tuple to a regular erlang tuple.

iex(1)> {:ok, client} = EdgeDB.start_link()
iex(2)> nt = EdgeDB.query_required_single!(client, "select (a := 1, b := 'a', c := [3])")
iex(3)> EdgeDB.NamedTuple.to_tuple(nt)
{1, "a", [3]}
