pub struct UInt<U, B> { /* private fields */ }
Expand description
UInt
is defined recursively, where B
is the least significant bit and U
is the rest
of the number. Conceptually, U
should be bound by the trait Unsigned
and B
should
be bound by the trait Bit
, but enforcing these bounds causes linear instead of
logrithmic scaling in some places, so they are left off for now. They may be enforced in
future.
In order to keep numbers unique, leading zeros are not allowed, so UInt<UTerm, B0>
is
forbidden.
§Example
use typenum::{UInt, UTerm, B0, B1};
type U6 = UInt<UInt<UInt<UTerm, B1>, B1>, B0>;
