Struct ed25519_dalek::pkcs8::spki::der::asn1::Utf8StringRef

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

Available on crate feature pkcs8 only.

ASN.1 UTF8String type.

Supports the full UTF-8 encoding.

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

You are free to use 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

impl<'a> Utf8StringRef<'a>

pub fn new<T>(input: &'a T) -> Result<Utf8StringRef<'a>, Error>

where T: AsRef<[u8]> + ?Sized,

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

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

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

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

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

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(utf_string: Utf8StringRef<'a>) -> AnyRef<'a>

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

This method tests for self and other values to be equal, and is used by ==.

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

This method 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

This method tests less than (for self and other) and is used by the < operator.

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

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

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

This method tests greater than (for self and other) and is used by the > operator.

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

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