Crate scolapasta_int_parse

Parse a given byte string and optional radix into an i64.

parse wraps i64::from_str_radix by normalizing the input byte string:

• Assert the byte string is ASCII and does not contain NUL bytes.
• Parse the radix to ensure it is in range and valid for the given input byte string.
• Trim leading whitespace.
• Accept a single, optional + or - sign byte.
• Parse a literal radix out of the string from one of 0b, 0B, 0o, 0O, 0d, 0D, 0x, or 0X. If the given radix is Some(_), the radix must match the embedded radix literal. A 0 prefix of arbitrary length is interpreted as an octal literal.
• Remove (“squeeze”) leading zeros.
• Collect ASCII alphanumeric bytes and filter out underscores.

The functions and types in this crate can be used to implement Kernel#Integer in Ruby.

Structs

• ArgumentError
  Error that indicates the byte string input to parse was invalid.
• InvalidRadixError
  Error that indicates the radix input to parse was invalid.
• Radix
  A checked container for the radix to use when converting a string to an integer.

Enums

• Error
  Sum type for all possible errors from this crate.
• InvalidRadixExceptionKind
  An enum describing which type of Ruby Exception an InvalidRadixError should be mapped to.

Functions

• parse
  Parse a given byte string and optional Radix into an i64.
