Optimizing a Math Expression Parser in Rust
Optimizing a Math Expression Parser in Rust Optimizing a Math Expression Parser in Rust Table of contents In a previous post I explored how to optimize file parsing for max speed. This time, we’ll look at a different, self-contained problem: writing a math expression parser in Rust, and making it as fast and memory-efficient as possible. Let’s say we want to parse simple math expressions with addition, subtraction, and parentheses. For example: 4 + 5 + 2 - 1 => 10 (4 + 5) - (2 + 1) => 6 (1
