Crate blaze_rs

This crate wraps the blaze library which is geared towards efficient and cross-platform 2D sprite drawing using OpenGL. Supported features:

• Dynamic batched sprite drawing
• Static batched sprite drawing
• Immediate drawing
• Texture loading
• Render targets
• Custom shaders
• Screenshot saving

Modules

blend	Defines blending-related functionality.
dynamic	Dynamic batched drawing. Designed for moving sprites.
immediate	Immediate-mode drawing.
rendertarget	Render target support.
shader	Custom shader support.
static	Static batched drawing. Designed for static geometry.
texture	Texture loading and saving.

Structs

Color	Represents a RGBA color.
Rectangle	A rectangle which has it's top-left corner position, width and height expressed in floats.
SpriteQuad	Underlying sprite quad data structure used by VAOs (vertex array objects).
Vector2	Two-dimensional float vector.
Vector4	Four-dimensional float vector.
Vertex	Underlying vertex data structure used by VAOs (vertex array objects).

Enums

SpriteFlip

Defines supported flip modes that can be used when the sprite is drawn.

Functions

clear	Clears the current framebuffer.
get_last_error	Returns last API error information string. The same string is returned from API calls which return Result<..., String>. Note: error string may be empty even if an API call failed, the output Result<..., String> will return an Err("Unknown error") in that case.
load	Loads OpenGL functions used by this library. Requires an active window with an OpenGL context (version 3.0 core and above).
set_clear_color	Sets the color which is used for clearing the framebuffer.
set_viewport	Sets viewport dimensions. All sprite position and size calculations will be based on them. In most cases, you should pass the window size in pixels here, or a scaled value for pixel-art based games, for example.

Type Definitions

CallResult	Alias for Result<(), String>.
GLProcLoader	Defines a type for OpenGL procedure loader.
