Struct CheckpointBoundaryConstraint 

pub struct CheckpointBoundaryConstraint { /* private fields */ }

Legality of computing a span from M to a boundary N and continuing with a nonempty suffix. These constrain span lengths, not absolute token positions. An implementation that additionally requires absolute-position alignment cannot use this contract without a separate, versioned boundary declaration. Plans intersect all declarations; validating only the first span is insufficient.

Implementations

impl CheckpointBoundaryConstraint

pub fn new( prefix: CheckpointTokenSpanConstraint, suffix: CheckpointTokenSpanConstraint, ) -> Result<Self, VNextError>

pub const fn any_positive() -> Self

pub const fn prefix(&self) -> CheckpointTokenSpanConstraint

pub const fn suffix(&self) -> CheckpointTokenSpanConstraint

pub fn permits(&self, prefix_tokens: u64, prompt_tokens: u64) -> bool

pub fn permits_from( &self, processed_tokens: u64, boundary_tokens: u64, prompt_tokens: u64, ) -> bool

Validates both actual execution spans, including after restoration to M. Neither a zero-length capture frame nor an empty suffix is permitted.
