A Swift wrapper for the CDB (Constant Database) implementation from howerj/cdb, providing a native Swift interface for creating and querying constant key-value databases.

Add this package to your Swift project dependencies:

// In your Package.swift
dependencies: [
    .package(url: "https://github.com/aisk/swift-cdb.git", from: "0.1.0"),
]

import CDB

// Open a CDB file and read values
do {
    let db = try CDB(filename: "example.cdb", mode: .read)

    // Read string value
    let value: String? = try db.get(key: "some_key")
    print("Value: \(value ?? "not found")")

    try db.close()
} catch {
    print("Error: \(error)")
}

• init(filename: String, mode: Mode) throws - Open a CDB file
• add(key: String, value: String) throws - Add a string value
• add(key: String, value: Data) throws - Add binary data
• get(key: String, at index: UInt64 = 0) throws -> String? - Get string value
• get(key: String, at index: UInt64 = 0) throws -> Data? - Get binary data
• count(key: String) throws -> UInt64 - Count values for a key
• close() throws - Close the database
• subscript(key: String) -> String? - Dictionary-like access

• .read - Open for reading only
• .write - Open for writing (creates new database)
