: Signed LEB128 (SLEB128) requires sign-extension logic during decoding and checking the sign bit of the last 7-bit chunk during encoding. Performance : For high-performance needs, consider using the library available on , which handles signed integers and edge cases efficiently. 624 in binary: 1001110000 : Useful for reading

624 in binary: 1001110000

: Useful for reading LEB128 sequences from larger binary streams without loading the entire file into memory. Why Use LEB128?
