Addressing solana-labs/solana#23620

Design goals

  • No dependencies
  • No panic sources such as: Direct array access, unwrap, assert
  • Explicit bounds checks, overlap checks, arithmetic checks
  • Strict numeric limits on string lengths, number of sections etc.
  • Avoid memory allocation, using references or pointers instead
  • Minimal parser state, using mem::transmute instead

Specification
