Struct openssl::asn1::Asn1String
source · pub struct Asn1String(/* private fields */);
Expand description
Primary ASN.1 type used by OpenSSL
Almost all ASN.1 types in OpenSSL are represented by ASN1_STRING structures. This implementation uses ASN1_STRING-to_UTF8 to preserve compatibility with Rust’s String.
Methods from Deref<Target = Asn1StringRef>§
sourcepub fn as_utf8(&self) -> Result<OpensslString, ErrorStack>
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.
This corresponds to ASN1_STRING_to_UTF8
.
sourcepub fn as_slice(&self) -> &[u8] ⓘ
pub fn as_slice(&self) -> &[u8] ⓘ
Return the string as an array of bytes.
The bytes do not directly correspond to UTF-8 encoding. To interact with
strings in rust, it is preferable to use as_utf8
This corresponds to ASN1_STRING_get0_data
.
sourcepub fn len(&self) -> usize
pub fn len(&self) -> usize
Returns the number of bytes in the string.
This corresponds to ASN1_STRING_length
.
