Module parser 

Expression parser for mathematical expressions.

This module provides a parser for converting string representations of mathematical expressions into Expression objects.

Supported Syntax

• Numbers: 42, 3.14, -2.5, 1e-10
• Variables: x, theta, alpha_1
• Constants: pi, e, I (imaginary unit)
• Operators: +, -, *, /, ^ (power)
• Functions: sin, cos, tan, exp, log, sqrt, abs
• Parentheses: (, )

Examples

use quantrs2_symengine_pure::parser::parse;

let expr = parse("sin(x) + cos(y)").unwrap();
let expr2 = parse("x^2 + 2*x + 1").unwrap();

Functions

parse

Parse a mathematical expression from a string.

parse_many
