Struct der::asn1::TeletexStringRef

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

ASN.1 TeletexString type.

Supports a subset the ASCII character set (described below).

For UTF-8, use Utf8StringRef instead. For the full ASCII character set, use Ia5StringRef.

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

Supported characters

The standard defines a complex character set allowed in this type. However, quoting the ASN.1 mailing list, “a sizable volume of software in the world treats TeletexString (T61String) as a simple 8-bit string with mostly Windows Latin 1 (superset of iso-8859-1) encoding”.

Implementations

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 TeletexStringRef<'_>

const TAG: Tag = Tag::TeletexString

ASN.1 tag

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

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

Converts to this type from the input type.

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

fn from(teletex_string: TeletexStringRef<'a>) -> AnyRef<'a>

Converts to this type from the input type.

impl<'a> Ord for TeletexStringRef<'a>

fn cmp(&self, other: &TeletexStringRef<'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 TeletexStringRef<'a>

fn eq(&self, other: &TeletexStringRef<'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 TeletexStringRef<'a>

fn partial_cmp(&self, other: &TeletexStringRef<'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.

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.
