Struct Encoder

pub struct Encoder<'a> { /* private fields */ }

Represents MessagePack serialization implementation.

Note

MessagePack has no specification about how to encode variant types. Thus we are free to do whatever we want, so the given chose may be not ideal for you.

Every Rust variant value can be represented as a tuple of index and a value.

All instances of ErrorKind::Interrupted are handled by this function and the underlying operation is retried.

Implementations

impl<'a> Encoder<'a>

pub fn new(wr: &'a mut dyn Write) -> Encoder<'a>

Creates a new MessagePack encoder whose output will be written to the writer specified.

Trait Implementations

impl<'a> Encoder for Encoder<'a>

fn emit_enum<F>(&mut self, _name: &str, f: F) -> Result<(), Error>

where F: FnOnce(&mut Self) -> Result<(), Error>,

Encodes and attempts to write the enum value into the Write.

Currently we encode variant types as a tuple of id with array of args, like: [id, [args…]]

where F: FnOnce(&mut Self) -> Result<(), Error>,

fn emit_enum_variant_arg<F>(&mut self, _idx: usize, f: F) -> Result<(), Error>

where F: FnOnce(&mut Self) -> Result<(), Error>,

Encodes and attempts to write a concrete variant value arguments.
