# `Backplane.JsonSchema.Sigil`

Compile-time sigils for static JSON Schema literals.

The primary sigil is `~X`, chosen to avoid the common `~J` conflict with
Jason while still feeling mnemonic for Backplane.JsonSchema.

The sigil body is parsed as Elixir, not JSON, so the most ergonomic form is
an Elixir map or boolean literal.

## Examples

    iex> import Backplane.JsonSchema.Sigil, only: [sigil_X: 2]
    iex> schema = ~X|%{"type" => "integer"}|
    iex> Backplane.JsonSchema.validate(schema, 1)
    :ok

    iex> import Backplane.JsonSchema.Sigil, only: [sigil_X: 2]
    iex> schema = ~X|%{"type" => "string", "format" => "email"}|f
    iex> {:error, [_]} = Backplane.JsonSchema.validate(schema, "not-an-email")
