Function scratchstack_wrapper_aws_c_common::aws_byte_cursor_utf8_parse_u64

pub unsafe extern "C" fn aws_byte_cursor_utf8_parse_u64(
    cursor: aws_byte_cursor,
    dst: *mut u64
) -> c_int

Read entire cursor as ASCII/UTF-8 unsigned base-10 number. Stricter than strtoull(), which allows whitespace and inputs that start with “0x”

Examples: “0” -> 0 “123” -> 123 “00004” -> 4 // leading zeros ok

Rejects things like: “-1” // negative numbers not allowed “1,000” // only characters 0-9 allowed “” // blank string not allowed “ 0 “ // whitespace not allowed “0x0” // hex not allowed “FF” // hex not allowed “999999999999999999999999999999999999999999” // larger than max u64
