Expand description
All draw data to render a Dear ImGui frame.
Fields
total_idx_count: i32
For convenience, sum of all draw list index buffer sizes.
total_vtx_count: i32
For convenience, sum of all draw list vertex buffer sizes.
display_pos: [f32; 2]
Upper-left position of the viewport to render.
(= upper-left corner of the orthogonal projection matrix to use)
display_size: [f32; 2]
Size of the viewport to render.
(= display_pos + display_size == lower-right corner of the orthogonal matrix to use)
framebuffer_scale: [f32; 2]
Amount of pixels for each unit of display_size.
Based on io.display_frame_buffer_scale. Typically [1.0, 1.0] on normal displays, and [2.0, 2.0] on Retina displays, but fractional values are also possible.

Returns an iterator over the draw lists included in the draw data.
Returns the number of draw lists included in the draw data.
Converts all buffers from indexed to non-indexed, in case you cannot render indexed buffers.
This is slow and most likely a waste of resources. Always prefer indexed rendering!
Scales the clip rect of each draw command.
Can be used if your final output buffer is at a different scale than imgui-rs expects, or if there is a difference between your window resolution and framebuffer resolution.
