Encoding trait.

This trait describes how to encode a given type.

Required Methods

fn encoded_len(&self) -> Result<usize, Error>

Get the length of this type encoded in bytes, prior to Base64 encoding.

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

Encode this value using the provided Writer.

Provided Methods

fn encoded_len_prefixed(&self) -> Result<usize, Error>

Return the length of this type after encoding when prepended with a uint32 length prefix.

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

Encode this value, first prepending a uint32 length prefix set to Encode::encoded_len.

Object Safety

This trait is not object safe.

Implementations on Foreign Types

impl Encode for &str

Encode a string as described in RFC4251 § 5:

Arbitrary length binary string. Strings are allowed to contain arbitrary binary data, including null characters and 8-bit characters. They are stored as a uint32 containing its length (number of bytes that follow) and zero (= empty string) or more bytes that are the value of the string. Terminating null characters are not used.

Strings are also used to store text. In that case, US-ASCII is used for internal names, and ISO-10646 UTF-8 for text that might be displayed to the user. The terminating null character SHOULD NOT normally be stored in the string. For example: the US-ASCII string “testing” is represented as 00 00 00 07 t e s t i n g. The UTF-8 mapping does not alter the encoding of US-ASCII characters.
