Struct openssl::asn1::Asn1StringRef

pub struct Asn1StringRef(_);

Reference to Asn1String

Methods

impl Asn1StringRef

pub fn as_utf8(&self) -> Result<OpensslString, ErrorStack>

Converts the ASN.1 underlying format to UTF8

ASN.1 strings may utilize UTF-16, ASCII, BMP, or UTF8. This is important to consume the string in a meaningful way without knowing the underlying format.

Important traits for &'a [u8]

impl<'a> Read for &'a [u8]impl<'a> Write for &'a mut [u8]

pub fn as_slice(&self) -> &[u8]

Return the string as an array of bytes

The bytes do not directly corespond to UTF-8 encoding. To interact with strings in rust, it is preferable to use as_utf8

pub fn len(&self) -> usize

Return the length of the Asn1String (number of bytes)
