go reflect tool

## Install

```shell

go get github.com/chyroc/reflectx

```

## Usage

- check reflect.Value is some type

```go

// true

reflectx.IsUnsignedInt(reflect.ValueOf(uint(1)))

// false

reflectx.IsSignedInt(reflect.ValueOf(uint(1)))

// true

reflectx.IsInt(reflect.ValueOf(int(1)))

reflectx.IsInt(reflect.ValueOf(uint(1)))

// true

reflectx.IsBool(reflect.ValueOf(false))

```

- convert reflect.Value to some type

```go

// 1, nil

reflectx.ToInt64(reflect.ValueOf(uint(1)))

// 0, err

reflectx.ToInt64(reflect.ValueOf(false))

// true, nil

reflectx.ToBool(reflect.ValueOf(true))

// false, err

reflectx.ToBool(reflect.ValueOf(1))

// &true, nil

reflectx.ToPtr(reflect.ValueOf(true))

// &uint(1), err

reflectx.ToPtr(reflect.ValueOf(uint(1)))

```

- set value to reflect.Value

```go

var i int // -> 1

reflectx.SetInt(reflect.ValueOf(&i), 1)

var i uint // -> 2

reflectx.SetUint(reflect.ValueOf(&i), 2)

var i float6 // -> 1.1

reflectx.SetFloat(reflect.ValueOf(&i), 1.1)

```
