pub fn logos_add_exact(
a: impl Into<LogosInt>,
b: impl Into<LogosInt>,
) -> LogosIntExpand description
Exact Int arithmetic for GENERATED code (overflow ruling v2, stage 2):
the i64 fast path is a single checked op; overflow spills to the
promoting crate::types::LogosInt — the AOT’s mirror of the
interpreter’s Int→BigInt promotion. impl Into<LogosInt> lets an
already-promoted operand chain through the same helper unchanged.
