Trait ed::Encode [−][src]
pub trait Encode {
fn encode_into<W: Write>(&self, dest: &mut W) -> Result<()>;
fn encoding_length(&self) -> Result<usize>;
fn encode(&self) -> Result<Vec<u8>> { ... }
}Expand description
A trait for values that can be encoded into bytes deterministically.
Required methods
Writes the encoded representation of the value to the destination
writer. Can error due to either a write error from dest, or an
encoding error for types where invalid values are possible.
It may be more convenient to call encode which
returns bytes, however encode_into will often be more efficient since
it can write the encoding without necessarily allocating a new
Vec<u8>.
fn encoding_length(&self) -> Result<usize>
fn encoding_length(&self) -> Result<usize>
Calculates the length of the encoding for this value. Can error for types where invalid values are possible.

Encodes the integer as fixed-size big-endian bytes.
Returns the size of the integer in bytes. Will always

Encodes the boolean as a single byte: 0 for false or 1 for true.
Always returns Ok(1).
Encodes as a 0 byte for None, or as a 1 byte followed by the encoding of
the inner value for Some.
Length will be 1 for None, or 1 plus the encoding length of the inner
value for Some.
Always returns Ok(0).
