• NonZeroU8
  An integer that is known not to equal zero.
• NonZeroU16
  An integer that is known not to equal zero.
• NonZeroU32
  An integer that is known not to equal zero.
• NonZeroU64
  An integer that is known not to equal zero.
• NonZeroU128
  An integer that is known not to equal zero.
• NonZeroUsize
  An integer that is known not to equal zero.
• ParseFloatError
  An error which can be returned when parsing a float.
• ParseIntError
  An error which can be returned when parsing an integer.
• TryFromIntError
  The error type returned when a checked integral type conversion fails.
• Wrapping
  Provides intentionally-wrapped arithmetic on T.

Enums

• FpCategory
  A classification of floating point numbers.
• IntErrorKind
  Enum to store the various types of errors that can cause parsing an integer to fail.

Constants

• ASCII_CASE_MASK 🔒
  If 6th bit is set ascii is lower case.

Traits

• FromStrRadixHelper 🔒

Functions

• can_not_overflowExperimental
  Determines if a string of text of that length of that radix could be guaranteed to be stored in the given type T. Note that if the radix is known to the compiler, it is just the check of digits.len that is done at runtime.
• from_str_radix 🔒
