Struct Asn1String 

pub struct Asn1String(/* private fields */);

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>

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.

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.

pub fn len(&self) -> usize

Returns the number of bytes in the string.

This corresponds to ASN1_STRING_length.

pub fn is_empty(&self) -> bool

Determines if the string is empty.

Trait Implementations

impl AsRef<Asn1StringRef> for Asn1String

fn as_ref(&self) -> &Asn1StringRef

Converts this type into a shared reference of the (usually inferred) input type.

impl Borrow<Asn1StringRef> for Asn1String

fn borrow(&self) -> &Asn1StringRef

Immutably borrows from an owned value.

impl Deref for Asn1String

type Target = Asn1StringRef

The resulting type after dereferencing.

fn deref(&self) -> &Asn1StringRef

Dereferences the value.

impl DerefMut for Asn1String

fn deref_mut(&mut self) -> &mut Asn1StringRef

Mutably dereferences the value.

impl Drop for Asn1String

fn drop(&mut self)

Executes the destructor for this type.

impl ForeignType for Asn1String

type CType = ASN1_STRING

The raw C type.

type Ref = Asn1StringRef

The type representing a reference to this type.

unsafe fn from_ptr(ptr: *mut ASN1_STRING) -> Asn1String

Constructs an instance of this type from its raw type.

fn as_ptr(&self) -> *mut ASN1_STRING

Returns a raw pointer to the wrapped value.

impl Send for Asn1String

impl Sync for Asn1String

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
