Struct Asn1StringRef 

pub struct Asn1StringRef(/* private fields */);

A reference to an Asn1String.

Implementations

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.

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 Debug for Asn1StringRef

fn fmt(&self, fmt: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl ForeignTypeRef for Asn1StringRef

type CType = ASN1_STRING

The raw C type.

unsafe fn from_ptr<'a>(ptr: *mut Self::CType) -> &'a Self

Constructs a shared instance of this type from its raw type.

unsafe fn from_ptr_mut<'a>(ptr: *mut Self::CType) -> &'a mut Self

Constructs a mutable reference of this type from its raw type.

fn as_ptr(&self) -> *mut Self::CType

Returns a raw pointer to the wrapped value.

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.
