Struct Int512 

pub struct Int512(/* private fields */);

Hand-rolled fixed-width two’s-complement signed integer.

Implementations

impl Int512

pub const fn from_str_radix(s: &str, radix: u32) -> Result<Int512, ()>

Parse a signed decimal magnitude from s. Mirrors i128::from_str_radix in shape: accepts an optional leading -, then ASCII digits. Currently only radix == 10 is supported; any other value returns Err(()). const fn so the consts module can parse the build- time generated string literals.

pub const fn pow(self, exp: u32) -> Int512

Integer power: self^exp via right-to-left binary exponentiation. Wraps on overflow (same semantics as i128::wrapping_pow). const fn; runs at compile time when both inputs are const.

pub const fn to_i128_checked(self) -> Option<i128>

Exact i128 value, or None if it does not fit.

pub const fn to_u128_checked(self) -> Option<u128>

Exact u128 value, or None if negative / too large.

pub const fn from_i128(v: i128) -> Int512

Builds from a signed 128-bit value.

pub const fn from_limbs_le(limbs: [u128; 4]) -> Int512

Builds directly from the limb array. The limbs are interpreted as a little-endian two’s-complement signed integer (i.e. the same in-memory shape decl_wide_int! uses). Useful for the serde binary path, which transports the raw limbs unchanged.

pub const fn limbs_le(self) -> [u128; 4]

Read-only access to the underlying limbs. The little-endian two’s-complement signed shape; symmetric with Self::from_limbs_le.

pub const fn from_u128(v: u128) -> Int512

Builds from an unsigned 128-bit value.
