Trait Accumulate 

pub trait Accumulate<T>: Default {
    // Required method
    fn try_done(self, field: &'static str) -> Result<T, Error>;
}

Accumulate values during deserialization

A type implementing Accumulate<T> is used to accumulate a value of type T.

Required Methods

fn try_done(self, field: &'static str) -> Result<T, Error>

Convert the accumulator into the final value, or return an error

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
