Crate big_int

big_int - Arbitrary precision, arbitrary base integer arithmetic library.

Structs

• BigInt
  BigInt: represents an arbitrary-size integer in base BASE.

Enums

• BigIntError
• ParseError

Constants

• BASE64_ALPHABET
• STANDARD_ALPHABET

Traits

• GetBack
  Safely retrieve items from a collection with negative indexing.
• GetBackMut
  Safely retrieve a mutable reference from a collection with negative indexing.

Functions

• base64_decode
  Decode a base64 string into an array of bytes.
• base64_encode
  Encode an array of bytes into base64 data.

Type Aliases

• Digit
  change these if you want to represent bases larger than 256
• DoubleDigit
  this must be twice the size of Digit (for overflow prevention)
