pub struct Int { /* private fields */ }
Available on crate feature alloc
only.
Expand description
Signed arbitrary precision ASN.1 INTEGER
type.
Provides heap-allocated storage for big endian bytes which comprise an
signed integer value.
Intended for use cases like very large integers that are used in
cryptographic applications (e.g. keys, signatures).
Create a new Int
from a byte slice.
Borrow the inner byte slice which contains the least significant bytes
of a big endian integer value with all leading ones stripped.
Get the length of this Int
in bytes.
Is the inner byte slice empty?

header) when
encoded as ASN.1 DER.
Encode value (sans
Tag

Length
header) as ASN.1 DER using the
provided
Writer

The resulting type referencing back to Self
Creates a new object referencing back to the self for storage
This method tests for self
and other
values to be equal, and is used
by ==
.
This method tests for !=
. The default implementation is almost always
sufficient, and should not be overridden without very good reason.
This method returns an ordering between
self
and
other
values if one exists.

self
and
other
) and is used by the
<
operator.
