Struct asn1::Tag

pub struct Tag { /* private fields */ }

Implementations

impl Tag

pub fn from_bytes(data: &[u8]) -> ParseResult<(Tag, &[u8])>

Parses a Tag from bytes and returns either the Tag and the remaining bytes from the input or an error.

pub fn as_u8(self) -> Option<u8>

Returns the tag’s representation (including tag class and constructed bits) as a u8 if the value component fits in a short form (value < 31) or None if this is a long-form tag.

Trait Implementations

impl Clone for Tag

fn clone(&self) -> Tag

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Tag

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

Formats the value using the given formatter.

impl Hash for Tag

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for Tag

fn eq(&self, other: &Tag) -> 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.
