Module managed_hints 

Ergonomic managed memory hints API.

This module builds on the raw crate::memory_info::mem_advise and crate::memory_info::mem_prefetch functions to provide a higher-level, builder-style API for controlling unified memory migration behaviour.

Key types

• MigrationPolicy — declarative policy for common migration patterns.
• ManagedMemoryHints — builder for applying hints to a memory region.
• PrefetchPlan — batch multiple prefetch operations into one plan.

Example

// Assume `buf` is a UnifiedBuffer<f32> and `dev`/`stream` are valid.
// let hints = ManagedMemoryHints::from_unified(&buf);
// hints.set_read_mostly(&dev)?;
// hints.prefetch_to(&dev, &stream)?;
