Module `num`

Numeric traits and functions for the built-in numeric types.

Modules

complex
error Error types for conversion to integral types.
float_parse User-facing API for float parsing.
imp Numeric routines, separate from API.
int_macros
niche_types 100% perma-unstable
nonzero Definitions of integer that is known not to equal zero.
saturating Definitions of Saturating<T>.
traits
uint_macros
wrapping Definitions of Wrapping<T>.

Structs

Complex A complex number.
NonZero A value 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.
Saturating Provides intentionally-saturating arithmetic on T.
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 or converting an integer to fail.

Traits

ZeroablePrimitive A marker trait for primitive types which can be zero.

Functions

can_not_overflow 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_ascii_bytes_radix_panic
