Struct der::RawInteger

pub struct RawInteger<'a> { /* fields omitted */ }

Raw ASN.1 INTEGER type.

Provides direct access to the underlying DER-encoded bytes which comprise an integer value, intended for use cases like very large integers that are used for cryptographic keys. It can be used in order to convert them to the big integer representation of your choice.

Note that the Decodable and Encodable traits are impl'd for Rust's integer primitive types (i8 only for now) if you'd like to work directly with an integer value rather than decoding it yourself.

⚠️ Important Usage Notes ⚠️

This type does NOT ensure the value is canonically encoded according to DER's rules. If it's important for your use case that the message is valid ASN.1 DER, you MUST validate the value is canonically encoded yourself.
