BuiltinSerializers

Provides built-in TypeSerializer implementations for Kotlin's standard primitive and string types.

Supported types and their coercion rules:

Target type	Accepted raw types	Coercion notes
String	Any	Calls `toString()`
Int	Number, String	Numeric narrowing via `toInt()`; string parsed with `toIntOrNull()`
Long	Number, String	Numeric widening via `toLong()`; string parsed with `toLongOrNull()`
Double	Number, String	Numeric widening via `toDouble()`; string parsed with `toDoubleOrNull()`
Float	Number, String	Numeric narrowing via `toFloat()`; string parsed with `toFloatOrNull()`
Boolean	Boolean, String, Number	Strings must be `"true"` / `"false"` (case-insensitive); numbers use `!= 0`

Example:

val registry = SerializerRegistry()
BuiltinSerializers.registerAll(registry)

val intSer = registry.get(Int::class)!!
intSer.deserialize("42")   // 42
intSer.deserialize(42L)    // 42  (Long → Int coercion)

val boolSer = registry.get(Boolean::class)!!
boolSer.deserialize("true") // true
boolSer.deserialize(1)      // true  (non-zero → true)
