Crate surfman

Cross-platform GPU device and surface management.

You can use this crate to multithread a graphics application so that rendering happens on multiple threads, sharing textures among them in the most efficient manner. It may also be useful as a lightweight framework for just initializing rendering in native applications. This is in contrast to crates like SDL, GLFW, winit, and Glutin, all of which have a broader focus in that they manage windowing and the event loop as well.

Macros

declare_surfman

When using surfman, you should place this macro at the top of your crate, like so:

Structs

ContextAttributeFlags	Various flags that control attributes of the context and/or surfaces created from that context.
ContextAttributes	Attributes that control aspects of a context and/or surfaces created from that context.
ContextDescriptor	Information needed to create a context. Some APIs call this a “config” or a “pixel format”.
ContextID	A unique ID among all currently-allocated contexts.
GLVersion	Describes the OpenGL version that is requested when a context is created.
NativeContext	Wrapper for a native EGLContext.
SurfaceID	A unique ID per allocated surface.
SurfaceInfo	Various data about the surface.
SystemSurfaceInfo	Various data about the surface.

Enums

GLApi	The API (OpenGL or OpenGL ES).
SurfaceAccess	Specifies how and if the CPU has direct access to the surface data.
SurfaceType	Information specific to the type of surface: generic or widget.
