Struct multiformats::multicodec::Multicodec

pub struct Multicodec { /* fields omitted */ }

Type implements multicodec and unsigned-varint specs.

Implementations

impl Multicodec

pub fn from_code(code: u128) -> Result<Multicodec>

Create a new Multicodec from u128 code value.

pub fn from_slice(buf: &[u8]) -> Result<(Multicodec, &[u8])>

Convert incoming stream of bytes into multicodec value. Return remaining unparsed slice.

Return Error::Invalid if buf's content can't be recognised.

pub fn encode(&self) -> Result<Vec<u8>>

Encode Multicodec to unsigned-varint bytes.

pub fn encode_with<W>(&self, buf: &mut W) -> Result<usize> where
    W: Write, 

Similar to encode() but avoid allocation by using supplied buffer buf.

pub fn to_code(&self) -> u128

Return the underling code-value.
