Enum SsmRollbackMode 

pub enum SsmRollbackMode {
    Snapshot,
    Replay,
}

SSM verify-rollback mode (--ssm-rollback-mode, EXPERIMENTAL scaffold).

• Snapshot (the serve default, explicit in the CLI): every verify arm writes per-token h/conv state snapshots; a partial accept restores from intermediates[num_accepted - 1]. This is the only mode whose device path is wired — its sizing and behavior are pinned byte-for-byte.
• Replay: keep ONLY the pre-verify checkpoint blob per verify slot and cache the verify window’s per-token GDN INPUTS (the deinterleaved qkvz row each conv1d consumes plus the gate/beta row — the tensors the WY verify kernels read) in a small ring; a partial accept re-runs the accepted tokens from the checkpoint through the existing sequential recurrent path. Device wiring (capture + replay) is NOT implemented: a serve in this mode boots — the reserve shows the capacity win — and every speculative verify entry refuses loudly (SsmStatePool::require_verify_rollback_supported).

Trait Implementations

impl Clone for SsmRollbackMode

fn clone(&self) -> SsmRollbackMode

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SsmRollbackMode

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

Formats the value using the given formatter.

impl FromStr for SsmRollbackMode

fn from_str(s: &str) -> Result<Self, Self::Err>

SSOT parse for the --ssm-rollback-mode value (CLI validation and the serve publication both go through this).

type Err = String

The associated error which can be returned from parsing.

impl PartialEq for SsmRollbackMode

fn eq(&self, other: &SsmRollbackMode) -> 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.
