Struct ScheduledBasicBlock

pub struct ScheduledBasicBlock<'a> { /* private fields */ }

A ScheduledBasicBlock is a wrapper around a BasicBlock which includes a graph expressing the vector clock among the instructions according to the Quil specification.

If instruction A blocks instruction B (because of shared use of a frame), then there will be an edge from A to B in the graph.

Implementations

impl<'a> ScheduledBasicBlock<'a>

pub fn build( basic_block: BasicBlock<'a>, program: &'a Program, custom_handler: &mut InstructionHandler, ) -> ScheduleResult<Self>

Build a scheduled basic block from a basic block and a program.

pub fn get_dependency_graph(&self) -> &DependencyGraph

pub fn instructions(&'a self) -> &'a [&'a Instruction]

pub fn get_instruction(&self, node_id: usize) -> Option<&Instruction>

Return a particular-indexed instruction (if present).

pub fn label(&self) -> Option<&Target>

pub fn len(&self) -> usize

Return the count of executable instructions in this block.

pub fn is_empty(&self) -> bool

Return true if this block contains no executable instructions.

pub fn terminator(&self) -> &BasicBlockTerminator<'_>

pub fn basic_block(&self) -> &BasicBlock<'a>

impl<'p> ScheduledBasicBlock<'p>

pub fn as_schedule_seconds( &self, program: &Program, ) -> Result<ScheduleSeconds, ComputedScheduleError>

Compute the flattened schedule for this ScheduledBasicBlock in terms of seconds, using a default built-in calculation for the duration of scheduled instructions.

pub fn as_schedule<F, TimeUnit: Clone + PartialOrd + Add<TimeUnit, Output = TimeUnit> + Zero>( &self, program: &'p Program, get_duration: F, ) -> Result<Schedule<TimeUnit>, ComputedScheduleError>

where F: Fn(&'p Program, &'p Instruction) -> Option<TimeUnit>,

Compute the flattened schedule for this ScheduledBasicBlock using a user-provided closure for computation of instruction duration.

Return an error if the schedule cannot be computed from the information provided.
