A simple and generic **Go** map that is safe for concurrent use.

## Installation

```sh

go get -u github.com/mdawar/syncmap

```

## Usage

```go

// Create a map that is safe for concurrent use.

m := syncmap.New[string, int]()

// Create.

m.Set("a", 1)

m.Set("b", 2)

// Get stored value.

v, ok := m.Get("a")

fmt.Println(v)  // 1

fmt.Println(ok) // true

// Delete.

m.Delete("b")

// Map length.

m.Len()

// Clear the map (Remove all entries).

m.Clear()

// Iteration.

for k, v := range m.All() {

  fmt.Println("Key", k, "/", "Value", v)

}

```

```go

// Create a map with an initial capacity hint.

m := syncmap.NewWithCapacity[string, int](10_000)

// Equivalent to.

make(map[string]int, 10_000)

```

## Tests

```sh

go test -race -cover -vet=all

# If you have "just" installed.

# Or using make.

make test

```
