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.

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.

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

hex_u32_prefixed: Parses a u32 from a prefixed hex string.
hex_u32_unchecked: Parses a u32 from an unprefixed hex string without first checking for a prefix.
hex_u32_unprefixed: Parses a u32 from an unprefixed hex string.
hex_u128: Parses a u128 from a hex string.
hex_u128_prefixed: Parses a u128 from a hex string.
