Trait Stream 

pub trait Stream: Object {
    // Required method
    fn next(&self, cx: &mut Cx) -> Result<Option<Value>>;

    // Provided method
    fn close(&self, _cx: &mut Cx) -> Result<()> { ... }
}

A runtime object that yields values one at a time until it is closed.

Required Methods

fn next(&self, cx: &mut Cx) -> Result<Option<Value>>

Pulls the next value, or Ok(None) once the stream is exhausted.

Provided Methods

fn close(&self, _cx: &mut Cx) -> Result<()>

Releases any resources backing the stream; idempotent by default.

Dyn Compatibility

This trait is dyn compatible.

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