Struct SimpleTag 

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

These are tags like in SIMPLE-TLV.

The tag field consists of a single byte encoding a tag number from 1 to 254. The values ‘00’ and ‘FF’ are invalid.

The use case is that PIV (FIPS 201) data objects generally use BER-TLV, but, for historical reasons, label entries with “simple” tags (in particular, tag numbers larger than 30 are still encoded as single bytes.

Trait Implementations

impl Clone for SimpleTag

fn clone(&self) -> SimpleTag

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Decodable<'_> for SimpleTag

fn decode(decoder: &mut Decoder<'_>) -> Result<Self>

Attempt to decode this message using the provided decoder.

fn from_bytes(bytes: &'a [u8]) -> Result<Self>

Parse Self from the provided byte slice.

impl Encodable for SimpleTag

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

Compute the length of this value in bytes when encoded as BER-TLV

fn encode(&self, encoder: &mut Encoder<'_>) -> Result<()>

Encode this value as BER-TLV using the provided Encoder.

fn encode_to_slice<'a>(&self, buf: &'a mut [u8]) -> Result<&'a [u8]>

Encode this value to the provided byte slice, returning a sub-slice containing the encoded message.

impl PartialEq for SimpleTag

fn eq(&self, other: &SimpleTag) -> 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 TagLike for SimpleTag

fn embedding(self) -> Tag

To stick with one Error type, make sure the tag type can somehow or other be coerced into a BerTag.

fn assert_eq(self, expected: Self) -> Result<Self>

Assert that this Tag matches the provided expected tag.

fn with_value<V>(self, value: V) -> TaggedValue<V, Self>

Ergonomic way to get a TaggedValue for a given tag and value

impl TryFrom<u8> for SimpleTag

type Error = Error

The type returned in the event of a conversion error.

fn try_from(tag_number: u8) -> Result<Self>

Performs the conversion.
