Module traits

Various traits for converting numbers.

Traits

ConvertibleFrom

Tests whether a value of one type is convertible into a value of another.

Digits

Expresses a value as a Vec of digits, or reads a value from an iterator of digits.

ExactFrom

Converts a value from one type to another. If the conversion fails, the function panics.

ExactInto

Converts a value from one type to another. If the conversion fails, the function panics.

FromOtherTypeSlice

Converts a slice of one type of value to a single value of another type.

FromSciString

Converts a &str, possibly in scientific notation, to a number.

FromStringBase

Converts a string slice in a given base to a value.

HasHalf

Associates with Self a type that’s half Self’s size.

IntegerMantissaAndExponent

Converts a number to or from an integer mantissa and exponent.

IsInteger

Determines whether a number is an integer.

JoinHalves

Provides a function to join two pieces into a number. For example, two u32s may be joined to form a u64.

OverflowingFrom

Converts a value from one type to another, where if the conversion is not exact the result will wrap around. The result is returned along with a bool that indicates whether wrapping has occurred.

OverflowingInto

Converts a value from one type to another, where if the conversion is not exact the result will wrap around. The result is returned along with a bool that indicates whether wrapping has occurred.

PowerOf2DigitIterable

Creates an iterator over a value’s base-$2^k$ digits.

PowerOf2DigitIterator

An iterator over a value’s base-$2^k$ digits.

PowerOf2Digits

Expresses a value as a Vec of base-$2^k$ digits, or reads a value from an iterator of base-$2^k$ digits.

RawMantissaAndExponent

Converts a number to or from a raw mantissa and exponent.

RoundingFrom

Converts a value from one type to another, where the conversion is made according to a specified RoundingMode. An Ordering is also returned, indicating whether the returned value is less than, equal to, or greater than the original value.

RoundingInto

Converts a value from one type to another, where the conversion is made according to a specified RoundingMode. An Ordering is also returned, indicating whether the returned value is less than, equal to, or greater than the original value.

SaturatingFrom

Converts a value from one type to another, where if the conversion is not exact the result is set to the maximum or minimum value of the result type, whichever is closer.

SaturatingInto

Converts a value from one type to another, where if the conversion is not exact the result is set to the maximum or minimum value of the result type, whichever is closer.

SciMantissaAndExponent

Converts a number to or from a scientific mantissa and exponent.

SplitInHalf

Provides functions to split a number into two pieces. For example, a u64 may be split into two u32s.

ToSci

Converts a number to a string, possibly in scientific notation.

ToStringBase

Converts a number to a string using a specified base.

VecFromOtherType

Converts a slice of one type of value to a Vec of another type.

VecFromOtherTypeSlice

Converts a slice of one type of value to a Vec of another type.

WrappingFrom

Converts a value from one type to another. where if the conversion is not exact the result will wrap around.

WrappingInto

Converts a value from one type to another, where if the conversion is not exact the result will wrap around.
