Structs

SaturatingExperimental
Provides intentionally-saturating arithmetic on T.
NonZeroI8
An integer that is known not to equal zero.
NonZeroI16
An integer that is known not to equal zero.
NonZeroI32
An integer that is known not to equal zero.
NonZeroI64
An integer that is known not to equal zero.
NonZeroI128
An integer that is known not to equal zero.
NonZeroIsize
An integer that is known not to equal zero.
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 set ascii is upper 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 🔒
