Trait RelocatableStream 

pub trait RelocatableStream {
    // Required methods
    fn recording(&self) -> bool;
    fn has_outdated(&self) -> bool;
    fn relocation_need(&self) -> RelocationNeed;
    fn bytes_allocated(&self) -> u64;
    fn relocate(&mut self, reason: RelocationReason, failures: &mut ErrorGraph);
    fn cleanup_memory(&mut self, failures: &mut ErrorGraph);
}

One stream, as relocating its memory needs it: what a runtime whose streams share one way to finish their work (a scheduler, say) supplies per stream, leaving the rest of RelocatingStreams to that shared way.

Required Methods

fn recording(&self) -> bool

Whether any stream of the device records a graph.

fn has_outdated(&self) -> bool

Whether a growth left pages behind in the stream’s memory.

fn relocation_need(&self) -> RelocationNeed

Whether the stream’s memory wants a relocation, see MemoryManagement::relocation_need.

fn bytes_allocated(&self) -> u64

The bytes the stream’s memory holds from the device.

fn relocate(&mut self, reason: RelocationReason, failures: &mut ErrorGraph)

Move what the stream’s memory holds on outdated pages, once every stream’s work is done.

fn cleanup_memory(&mut self, failures: &mut ErrorGraph)

Give back every page the stream’s memory holds and nothing needs.

Dyn Compatibility

This trait is dyn compatible.

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