Module parse

Available on crate feature alloc only.

Parsing utilities.

Structs

• ContainsPrefixError
  Error when hex string contains a prefix (e.g. 0x).
• MissingPrefixError
  Error returned when a hex string is missing a prefix (e.g. 0x).
• ParseIntError
  Error with rich context returned when a string can’t be parsed as an integer.

Enums

• PrefixedHexError
  Error returned when parsing an integer from a hex string that is supposed to contain a prefix.
• UnprefixedHexError
  Error returned when parsing an integer from a hex string that is not supposed to contain a prefix.

Traits

• Integer
  Not strictly necessary but serves as a lint - avoids weird behavior if someone accidentally passes non-integer to the parse() function.
