Incorrect constructor usage for vk::DescriptorSetLayoutCreateInfo in documentation vs source code (initialization error)

[XavierBeheydt]

Problem

The line

vk::DescriptorSetLayoutCreateInfo layoutInfo({}, 1, &uboLayoutBinding);

appears in the documentation (e.g. in en/05_Uniform_buffers/00_Descriptor_set_layout_and_buffer.adoc). However, this usage leads to a compilation error when compiled as shown, with clang reporting:

Cannot initialize a member subobject of type 'const void *' with an rvalue of type 'int' clang(init_conversion_failed)

Details

• The code in the documentation differs from the code in the associated source file attachments/22_descriptor_layout.cpp, which uses:

  vk::DescriptorSetLayoutCreateInfo layoutInfo{.bindingCount = 1, .pBindings = &uboLayoutBinding};

• The constructor called in the documentation does not match the types expected for the vk::DescriptorSetLayoutCreateInfo, resulting in a conversion/init error on the {}/int argument.
• This creates confusion for users following the documentation, as the sample code fails to compile while the sample source does work.

Recommendation

• Update the documentation to match the working code from attachments/22_descriptor_layout.cpp.
• Use explicit member initialization via the designated initializer list for increased clarity and reduced errors:

  vk::DescriptorSetLayoutCreateInfo layoutInfo{.bindingCount = 1, .pBindings = &uboLayoutBinding};

• Optionally, provide a short explanation on constructor differences for clarity.
