enum Crysterm::OptimizationFlag

Overview

Rendering and drawing optimization flags.

Smart CSR: Attempt to perform CSR optimization on all possible elements, and not just on full-width ones, i.e. those with uniform cells to their sides. This is known to cause flickering with elements that are not full-width, but it is more optimal for terminal rendering.

Fast CSR: Enable CSR on any element within 20 columns of the screen edges on either side. It is faster than smart_csr, but may cause flickering depending on what is on each side of the element.

BCE: Attempt to perform back_color_erase optimizations for terminals that support it. It will also work with terminals that don't support it, but only on lines with the default background color. As it stands with the current implementation, it's uncertain how much terminal performance this adds at the cost of code overhead.
