Struct ordcode::SizeCalc

pub struct SizeCalc<P> { /* fields omitted */ }

Serialized object size calculator

Use as serde::Serializer on objects, then .size() will return serialized data size

Calculation process is inexpensive, for fixed-size objects it evaluates to compile-time constant, or a few len() method calls for variable-size objects (when compiling in release mode).

Implementations

impl<P> SizeCalc<P> where
    P: SerializerParams, 

#[must_use]pub fn new() -> Self

#[must_use]pub fn size(&self) -> usize

Returns calculated size

Trait Implementations

impl<P> Default for SizeCalc<P> where
    P: SerializerParams, 

pub fn default() -> Self

Returns the "default value" for a type.

impl<'a, P> Serializer for &'a mut SizeCalc<P> where
    P: SerializerParams, 

type Ok = ()

The output type produced by this Serializer during successful serialization. Most serializers that produce text or binary output should set Ok = () and serialize into an io::Write or buffer contained within the Serializer instance. Serializers that build in-memory data structures may be simplified by using Ok to propagate the data structure around.

type Error = Error

The error type when some error occurs during serialization.
