Trait SchemaValueStreamSource 

pub trait SchemaValueStreamSource: Send {
    // Required method
    fn next(
        &mut self,
    ) -> Pin<Box<dyn Future<Output = Result<Option<SchemaValueTree>, String>> + Send + '_>>;
}

A lazy guest producer. Local reads retain errors; forwarding a failure traps the producer because native streams have no error terminal.

Required Methods

fn next( &mut self, ) -> Pin<Box<dyn Future<Output = Result<Option<SchemaValueTree>, String>> + Send + '_>>

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
