Struct Signed

pub struct Signed<const BITS: usize, const LIMBS: usize>(/* private fields */);

Signed integer wrapping a ruint::Uint.

This signed integer implementation is fully abstract across the number of bits. It wraps a ruint::Uint, and co-opts the most significant bit to represent the sign. The number is represented in two’s complement, using the underlying Uint’s u64 limbs. The limbs can be accessed via the Signed::as_limbs() method, and are least-significant first.

Aliases

We provide aliases for every bit-width divisble by 8, from 8 to 256. These are located in crate::aliases and are named I256, I248 etc. Most users will want crate::I256.

Usage

// Instantiate from a number
let a = I256::unchecked_from(1);
// Use `try_from` if you're not sure it'll fit
let b = I256::try_from(200000382).unwrap();

// Or parse from a string :)
let c = "100".parse::<I256>().unwrap();
let d = "-0x138f".parse::<I256>().unwrap();

// Preceding plus is allowed but not recommended
let e = "+0xdeadbeef".parse::<I256>().unwrap();

// Underscores are ignored
let f = "1_000_000".parse::<I256>().unwrap();

// But invalid chars are not
assert!("^31".parse::<I256>().is_err());

// Math works great :)
let g = a * b + c - d;

// And so do comparisons!
assert!(e > a);

// We have some useful constants too
assert_eq!(I256::ZERO, I256::unchecked_from(0));
assert_eq!(I256::ONE, I256::unchecked_from(1));
assert_eq!(I256::MINUS_ONE, I256::unchecked_from(-1));

impl<const BITS: usize, const LIMBS: usize> Signed<BITS, LIMBS>

pub fn abs(self) -> Self

Computes the absolute value of self.

Overflow behavior

The absolute value of Self::MIN cannot be represented as Self and attempting to calculate it will cause an overflow. This means that code in debug mode will trigger a panic on this case and optimized code will return Self::MIN without a panic.

Panics

If rhs is 0.

pub fn wrapping_rem(self, rhs: Self) -> Self

Such wrap-around never actually occurs mathematically; implementation artifacts make x % y invalid for MIN / -1 on a signed type (where MIN is the negative minimal value). In such a case, this function returns 0.

Panics

If rhs is 0.

pub fn wrapping_div_euclid(self, rhs: Self) -> Self

Wrapping Euclidean division. Computes self.div_euclid(rhs), wrapping around at the boundary of the type.

Wrapping will only occur in MIN / -1 on a signed type (where MIN is the negative minimal value for the type). This is equivalent to -MIN, a positive value that is too large to represent in the type. In this case, this method returns MIN itself.

Panics

If rhs is 0.

pub fn rem_euclid(self, rhs: Self) -> Self

Calculates the least nonnegative remainder of self (mod rhs).

This is done as if by the Euclidean division algorithm – given r = self.rem_euclid(rhs), self = rhs * self.div_euclid(rhs) + r, and 0 <= r < abs(rhs).

Panics

If rhs is 0 or the division results in overflow.

pub fn overflowing_rem_euclid(self, rhs: Self) -> (Self, bool)

Panics

If rhs is 0.

Wrapping Euclidean remainder. Computes self.rem_euclid(rhs), wrapping around at the boundary of the type.

Wrapping will only occur in MIN % -1 on a signed type (where MIN is the negative minimal value for the type). In this case, this method returns 0.

If rhs is 0.

pub fn checked_rem_euclid(self, rhs: Self) -> Option<Self>

impl<const BITS: usize, const LIMBS: usize> ToSql for Signed<BITS, LIMBS>

Available on crate feature postgres only.

Convert to Postgres types.

Compatible Postgres data types are:

• BOOL, SMALLINT, INTEGER, BIGINT which are 1, 16, 32 and 64 bit signed integers respectively.
• OID which is a 32 bit unsigned integer.
• DECIMAL and NUMERIC, which are variable length.
• MONEY which is a 64 bit integer with two decimals.
• BYTEA, BIT, VARBIT interpreted as a big-endian binary number.
• CHAR, VARCHAR, TEXT as 0x-prefixed big-endian hex strings.
• JSON, JSONB as a hex string compatible with the Serde serialization.

Errors

Returns an error when trying to convert to a value that is too small to fit the number. Note that this depends on the value, not the type, so a Signed<256> can be stored in a SMALLINT column, as long as the values are less than $2^{16}$.

Implementation details

The Postgres binary formats are used in the wire-protocol and the the COPY BINARY command, but they have very little documentation. You are pointed to the source code, for example this is the implementation of the the NUMERIC type serializer: numeric.c.
