Struct CachingCompiler 

pub struct CachingCompiler { /* private fields */ }

Implementations

impl CachingCompiler

pub fn new<F>(capacity: usize, compile_fn: F) -> Self

where F: Fn(&TLExpr) -> Result<EinsumGraph, String> + Send + Sync + 'static,

Create a CachingCompiler with a custom compile function and cache capacity.

Arguments

• capacity – Maximum number of entries held in the LRU cache.
• compile_fn – A closure (or function) that compiles a TLExpr into an EinsumGraph, returning Err(String) on failure.

pub fn compile(&mut self, expr: &TLExpr) -> Result<EinsumGraph, String>

Compile an expression, returning the cached result when available.

Errors

Propagates any error produced by the underlying compile function on a cache miss.

pub fn compile_batch( &mut self, exprs: &[TLExpr], ) -> Vec<Result<EinsumGraph, String>>

Compile multiple expressions in order, sharing the cache across all of them.

Returns one Result per input expression in the same order.

pub fn cache_stats(&self) -> &CacheStats

Returns a reference to the current cache statistics.

pub fn invalidate(&mut self, expr: &TLExpr) -> bool

Invalidate the cached result for a specific expression.

Returns true if an entry was present and removed.

pub fn fingerprint(expr: &TLExpr) -> ExprFingerprint

Compute a structural ExprFingerprint for an expression.

Two structurally identical expressions will produce equal fingerprints.
