Struct AnalysisManager 

pub struct AnalysisManager { /* private fields */ }

An AnalysisManager is the primary entrypoint for performing analysis on a specific operation instance that it is constructed for.

It is used to manage and cache analyses for the operation, as well as those of child operations, via nested AnalysisManager instances.

This type is a thin wrapper around a pointer, and is meant to be passed by value. It can be cheaply cloned.

Implementations

impl AnalysisManager

pub fn new(op: OperationRef, instrumentor: Option<Rc<PassInstrumentor>>) -> Self

Create a new top-level AnalysisManager for op

pub fn get_cached_parent_analysis<A>( &self, parent: OperationRef, ) -> Option<Rc<A>>

where A: Analysis,

Query for a cached analysis on the given parent operation. The analysis may not exist and if it does it may be out-of-date.

pub fn get_analysis<A>(&self) -> Result<Rc<A>, Report>

where A: Analysis<Target = Operation>,

Query for the given analysis for the current operation.

pub fn get_analysis_for<A, O>(&self) -> Result<Rc<A>, Report>

where A: Analysis<Target = O>, O: 'static,

Query for the given analysis for the current operation of a specific derived operation type.

NOTE: This will panic if the current operation is not of type O.

pub fn get_cached_analysis<A>(&self) -> Option<Rc<A>>

where A: Analysis,

Query for a cached entry of the given analysis on the current operation.

pub fn get_child_analysis<A>(&self, op: OperationRef) -> Result<Rc<A>, Report>

where A: Analysis<Target = Operation>,

Query for an analysis of a child operation, constructing it if necessary.

pub fn get_child_analysis_for<A, O>(&self, op: &O) -> Result<Rc<A>, Report>

where A: Analysis<Target = O>, O: Op,

Query for an analysis of a child operation of a specific derived operation type, constructing it if necessary.

NOTE: This will panic if op is not of type O.

pub fn get_cached_child_analysis<A>( &self, child: &OperationRef, ) -> Option<Rc<A>>

where A: Analysis,

Query for a cached analysis of a child operation, or return None.

pub fn nest(&self, op: OperationRef) -> AnalysisManager

Get an analysis manager for the given operation, which must be a proper descendant of the current operation represented by this analysis manager.

pub fn invalidate(&self, preserved_analyses: &mut PreservedAnalyses)

Invalidate any non preserved analyses.

pub fn clear(&mut self)

Clear any held analyses.

pub fn defer_clear(&self) -> ResetAnalysesOnDrop

Clear any held analyses when the returned guard is dropped.

pub fn pass_instrumentor(&self) -> Option<Rc<PassInstrumentor>>

Returns a PassInstrumentor for the current operation, if one was installed.

Trait Implementations

impl Clone for AnalysisManager

fn clone(&self) -> AnalysisManager

Returns a duplicate of the value.

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

Performs copy-assignment from source.
