Struct der::asn1::Utf8String

source · [−]

pub struct Utf8String<'a> { /* private fields */ }

Expand description

ASN.1 UTF8String type.

Supports the full UTF-8 encoding.

Note that the Decodable and Encodable traits are impl’d for Rust’s str primitive, which decodes/encodes as a Utf8String.

You are free to use str instead of this type, however it’s still provided for explicitness in cases where it might be ambiguous with other ASN.1 string encodings such as PrintableString.
