Trait WritableDatumConfig 

pub trait WritableDatumConfig<T, O>
where
    O: Output,
{
    // Required method
    async fn write_datum(
        &self,
        datum: &T,
        output: &mut O,
    ) -> Result<(), O::Error>;
}

A helper object that writes other data, and not the object itself, on demand

Required Methods

async fn write_datum(&self, datum: &T, output: &mut O) -> Result<(), O::Error>

Writes an individual data point.

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.

Implementors

impl<F, T, W, O> WritableDatumConfig<T, O> for ExtractWritable<F>

where O: Output, for<'t> F: Fn(&'t T) -> W, W: Writable<O>,
