这是 HDF5 文件格式的一个 Swift 封装库。 HDF5 在科学界用于管理大量数据。目标是让从 Swift（包括 playgrounds）中读取和写入 HDF5 文件变得容易。

此示例展示了如何打开现有的 HDF5 文件并将数据写入现有的数据集。

import HDF5Kit

// Initialize the data
let dataWidth = 6
let dataHeight = 4
var data = [Double](repeating: 0.0, count: dataHeight * dataWidth)
for r in 0..<dataHeight {
    for c in 0..<dataWidth {
        data[r * dataWidth + c] = Double(r * dataWidth + c + 1)
    }
}

// Open an existing file
let path = "file.h5"
guard let file = File.open(path, mode: .readWrite) else {
    fatalError("Failed to open \(path)")
}

// Open an existing dataset
let datasetName = "dset"
guard let dataset = file.openDoubleDataset(datasetName) else {
    fatalError("Failed to open dataset \(datasetName)")
}

// Write the data
try dataset.write(data)

// Open an existing file
let path = "file.h5"
guard let file = File.open(path, mode: .readWrite) else {
    fatalError("Failed to open \(path)")
}

// Open an existing dataset
let datasetName = "dset"
guard let dataset = file.openStringDataset(datasetName) else {
    fatalError("Failed to open dataset \(datasetName)")
}

let data = dataset[1...3, 2...5]
