}
module Decode = {
let point = json =>
Aeson.Decode.{
x: field("x", float, json),
y: field("y", float, json)
}
let line = json =>
Aeson.Decode.{
start: field("start", point, json),
end_: field("end", point, json),
thickness: optional(x => field("thickness", int, x), json)
}
}
let data = "{
'start': { 'x': 1.1, 'y': -0.4 },
'end': { 'x': 5.3, 'y': 3.8 }
}"
let line = data->Js.Json.parseExn->Decode.line
