# encodedLength

The number of bytes required to store the encoded resources of an argument buffer.

## Declaration

```swift
var encodedLength: Int { get }
```

## Discussion

Discussion After creating an MTLArgumentEncoder instance, use this value to create the MTLBuffer instance that represents an argument buffer. id <MTLArgumentEncoder> encoder = [_function newArgumentEncoderWithBufferIndex:0]; id <MTLBuffer> buffer = [_device newBufferWithLength:encoder.encodedLength options:_options]; [encoder setArgumentBuffer:buffer offset:0];
