Trait bcder::encode::PrimitiveContent

pub trait PrimitiveContent {
    const TAG: Tag;

    fn encoded_len(&self, mode: Mode) -> usize;
    fn write_encoded<W: Write>(
        &self,
        mode: Mode,
        target: &mut W
    ) -> Result<(), Error>;

    fn to_encoded_bytes(&self, mode: Mode) -> Bytes { ... }

    fn encode_as(&self, tag: Tag) -> Primitive<'_, Self> { ... }
}

A type that is encoded as a primitive value.

This trait should be implemented for types that use primitive encoding. It defines, how the content octets of a single primitive value containing a value of the type are to be created. As a consequence, these types gain the encode and encode_as methods from their implementation of this trait.

Required Associated Constants

const TAG: Tag

The natural tag of an encoded value of this type.

Required Methods

fn encoded_len(&self, mode: Mode) -> usize

Returns the length of the encoded content of this type.

fn write_encoded<W: Write>(&self, mode: Mode, target: &mut W) -> Result<(), Error>

Writes the encoded content to a writer.

Provided Methods

fn to_encoded_bytes(&self, mode: Mode) -> Bytes

Encodes the value to bytes (useful when you need to sign a structure)

fn encode(&self) -> Primitive<'_, Self>

Returns a value encoder for this content using the natural tag.

This is identical to self.encode_as(Self::TAG)

fn encode_as(&self, tag: Tag) -> Primitive<'_, Self>

Returns a value encoder for this content using the given tag.

The returned value is a content encoder that produces a single primitive BER encoded value. The tag for this value is explicitely given via the tag argument.
