From 05179f5f649e1f4db39c47eba151094de55d05fa Mon Sep 17 00:00:00 2001 From: Cory Benfield Date: Fri, 5 Mar 2021 08:53:47 +0000 Subject: [PATCH 01/87] Define the PythonBytes type. This type encapsulates the Python byte string object. This requires a new data type, mostly because there is no natural "bucket of bytes" type in Swift without adding a Foundation dependency, which this module currently does not have. Instead, we can define a little wrapper that makes it as easy as possible to convert from existing types to the Python bytes object, and back again. --- PythonKit/Python.swift | 87 +++++++++++++++++++ PythonKit/PythonLibrary+Symbols.swift | 14 +++ Tests/PythonKitTests/PythonRuntimeTests.swift | 37 ++++++++ 3 files changed, 138 insertions(+) diff --git a/PythonKit/Python.swift b/PythonKit/Python.swift index 3df6176..21b8d4b 100644 --- a/PythonKit/Python.swift +++ b/PythonKit/Python.swift @@ -1430,3 +1430,90 @@ extension PythonObject : ExpressibleByArrayLiteral, ExpressibleByDictionaryLiter self.init(Dictionary(elements, uniquingKeysWith: { lhs, _ in lhs })) } } + +public struct PythonBytes : PythonConvertible, ConvertibleFromPython, Hashable { + public private(set) var pythonObject: PythonObject + + public init?(_ pythonObject: PythonObject) { + // We try to get the string/size pointers out.
