@spec parse(input :: binary()) :: {:ok, Tempus.Slot.t()} | {:error, any()}

Parses the sigil-like binary representation of a Tempus.Slot.

Examples

iex> Tempus.Sigils.parse("2021-03-30T06:35:40Z|2021-03-30T06:36:00Z")
{:ok, %Tempus.Slot{from: ~U[2021-03-30 06:35:40Z], to: ~U[2021-03-30 06:36:00Z]}}
iex> Tempus.Sigils.parse("foo|bar")
{:error, :invalid_format}

Handles the sigil ~I for Tempus.Slot. It returns a slot without interpolations and without escape characters, except for the escaping of the closing sigil character itself.

Allowed separators: |, →, ->, .. (might be surrounded by spaces)

Allowed modifiers:

• none — expects two instances of DateTime
• single letter, one of d, t, u — both values are expected to be of that type
• any combination of two letters d, t, u — the values are treated respectively
• g — the value types are to be guessed

Examples

iex> import Tempus.Sigils
iex> ~I(2021-03-30T06:35:40Z|2021-03-30T06:36:00Z)
%Tempus.Slot{from: ~U[2021-03-30 06:35:40Z], to: ~U[2021-03-30 06:36:00Z]}
iex> ~I(2021-03-30 → 2021-03-31)d

%Tempus.Slot{from: ~U[2021-03-30 00:00:00.000000Z], to: ~U[2021-03-30 23:59:59.999999Z]}
