LogosInt

Enum LogosInt 

Source
pub enum LogosInt {
    Small(i64),
    Big(Box<BigInt>),
}
Expand description

The exact integer for GENERATED code: i64 on the fast path, spilling to a heap [logicaffeine_base::BigInt] the moment a value escapes 64 bits — the AOT’s mirror of the interpreter’s Int→BigInt promotion (and of the JIT’s overflow side-exit). Every operation NORMALIZES: a big result that fits i64 downsizes to Small, so representation never leaks into ==/Ord.

Implementations§

Source§

impl LogosInt

Source

pub fn from_i64(x: i64) -> Self

Source

pub fn from_big(b: BigInt) -> Self

Source

pub fn from_literal(s: &str) -> Self

Parse a (possibly > 64-bit) decimal literal the codegen emitted.

Source

pub fn to_i64(&self) -> Option<i64>

The value as i64 when it fits.

Source

pub fn expect_i64(&self, what: &str) -> i64

The value as i64, or a LOUD canonical error — for sinks that are structurally 64-bit (indices, sizes, native call arguments).

Source

pub fn add(&self, rhs: &LogosInt) -> LogosInt

Source

pub fn sub(&self, rhs: &LogosInt) -> LogosInt

Source

pub fn mul(&self, rhs: &LogosInt) -> LogosInt

Source

pub fn div(&self, rhs: &LogosInt) -> Result<LogosInt, String>

Truncating division; Err on a zero divisor (the interp’s catchable “Division by zero”). i64::MIN / -1 promotes exactly.

Source

pub fn div_floor(&self, rhs: &LogosInt) -> Result<LogosInt, String>

Floor division — the quotient rounded toward NEGATIVE INFINITY (-7 // 2 → -4), the semantics of the // operator. Distinct from div, which truncates toward zero (-7 / 2 → -3); the two agree when the operands share a sign. Exact (promotes to BigInt); a zero divisor is a loud error.

Source

pub fn rem(&self, rhs: &LogosInt) -> Result<LogosInt, String>

Truncating remainder (sign of the dividend); i64::MIN % -1 is 0.

Source

pub fn pow(&self, exp: &LogosInt) -> Result<LogosInt, String>

Exponentiation with an integer exponent. Err on a negative exponent (an Int can’t hold the fractional result) or one too large to be a u32 power; overflow of the i64 fast path promotes to BigInt exactly. Mirrors the interpreter’s int_power.

Source

pub fn neg(&self) -> LogosInt
