Types mapping

The following table shows how Protobuf types are mapped to Elixir's ones.

Protobuf	Elixir
`int32`	`integer()`
`int64`	`integer()`
`uint32`	`integer()`
`uint64`	`integer()`
`sint32`	`integer()`
`sint64`	`integer()`
`fixed32`	`integer()`
`fixed64`	`integer()`
`sfixed32`	`integer()`
`sfixed64`	`integer()`
`float`	`float() \| :infinity \| :'-infinity' \| :nan`
`double`	`float() \| :infinity \| :'-infinity' \| :nan`
`bool`	`boolean()`
`string`	`String.t()`
`bytes`	`binary()`
`repeated`	`list(value_type)` where `value_type` is the type of the repeated field
`map`	`map()`
`oneof`	`{atom(), value_type}` where `atom()` is the name of the set field and where `value_type` is the type of the set field
`enum`	`atom() \| integer()`
`message`	`struct()`
