Enum PlannerMode 

pub enum PlannerMode {
    Disabled,
    Remap,
    Arena,
}

Selects the buffer-allocation strategy used by the planner entrypoint.

• Disabled short-circuits the planner and emits no replacements.
• Remap runs liveness-based pool reuse: groups buffers by (device, dtype, rounded_size) and lets disjoint-lifetime buffers share an underlying allocation.
• Arena packs all plannable buffers into one or two large per-(device, copy-lane) arenas using a TLSF allocator and rewrites each logical buffer as a Buffer::view into its lane’s arena (tinygrad parity).

Variants

Disabled

Skip the planner entirely. Each Buffer keeps its original allocation and is freed by lazy Drop. Useful for memory-debugging baselines.

Remap

Liveness-based pool reuse: groups buffers by (device, dtype, rounded_size) and lets disjoint-lifetime buffers share an underlying allocation via Arc<Buffer> swap.

Arena

Tinygrad-style packing: pack every plannable buffer into one or two per-(device, copy-lane) arenas using a TLSF allocator and rewrite each logical buffer as a fresh Buffer::view into its lane’s arena.

Trait Implementations

impl Clone for PlannerMode

fn clone(&self) -> PlannerMode

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for PlannerMode

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for PlannerMode

fn eq(&self, other: &PlannerMode) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
