Module parse_int 

Parsing utilities.

Structs

ParseIntError

Error with rich context returned when a string can’t be parsed as an integer.

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.
