AnyRef

Struct AnyRef 

Source
pub struct AnyRef<'a> { /* private fields */ }
Expand description

ASN.1 ANY: represents any explicitly tagged ASN.1 value.

This is a zero-copy reference type which borrows from the input data.

Technically ANY hasn’t been a recommended part of ASN.1 since the X.209 revision from 1988. It was deprecated and replaced by Information Object Classes in X.680 in 1994, and X.690 no longer refers to it whatsoever.

Nevertheless, this crate defines an ANY type as it remains a familiar and useful concept which is still extensively used in things like PKI-related RFCs.

Implementations§
