See above +for more details. + +### Struct generator + +The struct generator is a cleaner alternative to the global generator. + +The main difference is that you must call `gl::Gl::load_with` instead of +`gl::load_with`, and this functions returns a struct of type `Gl`. The OpenGL +functions are not static functions but member functions in this `Gl` struct. +This is important when the GL functions are associated with the current +context, as is true on Windows. + +The enumerations and types are still static and available in a similar way as +in the global generator. + +### Static generator + +The static generator generates plain old bindings. You don't need to load the +functions. + +This generator should only be used only if the platform you are compiling for +is guaranteed to support the requested API. Otherwise you will get a +compilation error. +For example, you can use it for WGL and OpenGL 1.1 on Windows or GLX and +OpenGL 1.3 on Linux, because Windows and Linux are guaranteed to provide +implementations for these APIs. + +You will need to manually provide the linkage. For example to use WGL or +OpenGL 1.1 on Windows, you will need to add +`#[link="OpenGL32.lib"] extern {}` somewhere in your code. + +### Custom Generators + +The `gl_generator` can be extended with custom generators. This is a niche +feature useful only in very rare cases. To create a custom generator, implement +the `gl_generator::Generator` trait. See the source of the +`gl_generator::generators` module for examples. + +Various utility functions are provided in the `generators` module, but the api +is unstable, so it has been placed behind a feature flag. In access these +functions, you will need to add the `"unstable_generator_utils"` feature to +your `Cargo.toml`: + +```toml +[build-dependencies.gl_generator] +version = "0.4.2" +features = ["unstable_generator_utils"] +``` + +## Extra features + +The global and struct generators will attempt to use fallbacks functions when +they are available. For example, if `glGenFramebuffers` cannot be loaded it will +also attempt to load `glGenFramebuffersEXT` as a fallback. + +## Changelog + +### v0.5.0 + +- Rename `Ns` to `API`, and expose at the top level +- Remove the need for clients to depend on the `khronos_api` crate by + determining the XML source based on the requested `API` +- Use a `(u8, u8)` instead of a string for the target version number +- Use a `Profile` enum instead of a string for the profile +- Remove unused fields from `Registry` +- Accept types satisfying `AsRef<[&str]>` for extension lists +- Separate parsing and generation stages in API +- Hide `registry::{Feature, Filter, Require, Remove, Extension}` types from the + public API +- Move `registry::{Fallbacks, Api, Profile}` types to top level module +- Remove `GlxOpcode::type` field +- Make `ty` fields on `Enum` and `Binding` take `Cow<'static, str>`s to reduce + allocations + +### v0.4.2 + +- Update crate metadata + +### v0.4.1 + +- Upgrade `khronos_api` to v1.0.0 + +### v0.4.0 + +- Upgrade `xml-rs` to v0.2.2 +- Use `raw::c_void` for `GLvoid` +- Remove `registry::{Group, EnumNs, CmdNs}` +- Remove `groups` field from `registry::Registry` +- Remove `is_safe` field from `registry::Cmd` +- Remove `comment` field from `registry::{Require, Remove, GlxOpcode}` +- Downgrade `khronos_api` to be a dev-dependency diff --git a/third_party/rust/gl_generator/generators/debug_struct_gen.rs b/third_party/rust/gl_generator/generators/debug_struct_gen.rs new file mode 100644 index 0000000000..98fbcef158 --- /dev/null +++ b/third_party/rust/gl_generator/generators/debug_struct_gen.rs @@ -0,0 +1,289 @@ +// Copyright 2015 Brendan Zabarauskas and the gl-rs developers +// +// Licensed under the Apache License, Version 2.0 (the "License");
