Struct der::asn1::Utf8StringRef

pub struct Utf8StringRef<'a> { /* private fields */ }

ASN.1 UTF8String type.

Supports the full UTF-8 encoding.

Note that the Decode and Encode traits are impl’d for Rust’s [str][prim@str] primitive, which decodes/encodes as a Utf8StringRef.

You are free to use [str][prim@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 PrintableStringRef.

This is a zero-copy reference type which borrows from the input data.

Implementations

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<'a> Debug for Utf8StringRef<'a>

Attempt to decode this message using the provided Reader.

impl<'a> Deref for Utf8StringRef<'a>

type Target = StrSlice<'a>

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.

impl<'a> Display for Utf8StringRef<'a>

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

Formats the value using the given formatter.

impl EncodeValue for Utf8StringRef<'_>

fn value_len(&self) -> Result<Length>

Compute the length of this value (sans Tag+Length header) when encoded as ASN.1 DER.

fn encode_value(&self, writer: &mut dyn Writer) -> Result<()>

Encode value (sans Tag+Length header) as ASN.1 DER using the provided Writer.

fn header(&self) -> Result<Header>

where Self: Tagged,

Get the Header used to encode this value.

impl FixedTag for Utf8StringRef<'_>

const TAG: Tag = Tag::Utf8String

ASN.1 tag

impl<'a> From<&Utf8StringRef<'a>> for Utf8StringRef<'a>

fn from(value: &Utf8StringRef<'a>) -> Utf8StringRef<'a>

Converts to this type from the input type.

impl<'a> From<Utf8StringRef<'a>> for AnyRef<'a>

fn from(printable_string: Utf8StringRef<'a>) -> AnyRef<'a>

Converts to this type from the input type.

impl<'a> From<Utf8StringRef<'a>> for String

fn from(s: Utf8StringRef<'a>) -> String

Converts to this type from the input type.

impl<'a> Ord for Utf8StringRef<'a>

fn cmp(&self, other: &Utf8StringRef<'a>) -> Ordering

This method returns an [Ordering] between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized + PartialOrd,

Restrict a value to a certain interval.

impl<'a> PartialEq for Utf8StringRef<'a>

fn eq(&self, other: &Utf8StringRef<'a>) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl<'a> PartialOrd for Utf8StringRef<'a>

fn partial_cmp(&self, other: &Utf8StringRef<'a>) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl<'a> TryFrom<AnyRef<'a>> for Utf8StringRef<'a>

type Error = Error

The type returned in the event of a conversion error.

fn try_from(any: AnyRef<'a>) -> Result<Utf8StringRef<'a>>

Performs the conversion.
