## Usage
|
|
|
|
### Dependency
|
|
|
|
This artifact is available in the Garrity Software Maven repository.
|
|
|
|
```scala
|
|
externalResolvers +=
|
|
"Garrity Software Releases" at "https://maven.garrity.co/gs"
|
|
|
|
val GsHex: ModuleID =
|
|
"gs" %% "gs-hex-v0" % "$VERSION"
|
|
```
|
|
|
|
### Byte Array Conversion
|
|
|
|
This library is based on two functions: `Hex.toHexString(Array[Byte])` and
|
|
`Hex.fromHexString(String)`.
|
|
|
|
```scala
|
|
import gs.hex.v0.Hex
|
|
|
|
val data: Array[Byte] = ???
|
|
val encoded: String = Hex.toHexString(data)
|
|
val decoded: Option[Array[Byte]] = Hex.fromHexString(encoded)
|
|
```
|
|
|
|
### Type Classes
|
|
|
|
This library provides `HexEncode[A]` and `HexDecode[A]` for encoding and
|
|
decoding arbitrary types as Hexadecimal strings. The types `Array[Byte]`,
|
|
`String`, `Boolean`, `Int` and `Long` are supported by default.
|
|
|
|
#### Example Type Class Implementations
|
|
|
|
```scala
|
|
given HexEncode[Array[Byte]] = new HexEncode[Array[Byte]] {
|
|
def toHexString(data: Array[Byte]): String = Hex.toHexString(data)
|
|
}
|
|
|
|
given HexDecode[Array[Byte]] = new HexDecode[Array[Byte]] {
|
|
def fromHexString(data: String): Option[Array[Byte]] =
|
|
Hex.fromHexString(data)
|
|
}
|
|
```
|
|
|
|
#### Example Type Class Usage
|
|
|
|
```scala
|
|
def encode[A](data: A)(using HexEncode[A]): String =
|
|
data.toHex()
|
|
|
|
def decode[A](data: String)(using HexDecode[A]): Option[A] =
|
|
data.fromHex()
|
|
```
