Struct CompiledSchema 

pub struct CompiledSchema { /* private fields */ }

A Schema paired with its precomputed [SymEntities].

Building [SymEntities] from a schema is expensive and depends only on the schema, not on any particular request environment. CompiledSchema computes it once so it can be reused across many request environments via CompiledSchema::sym_env, which is significantly cheaper than rebuilding the symbolic entities per environment (as SymEnv::new does).

Implementations

impl CompiledSchema

pub fn new(schema: &Schema) -> Result<Self>

Builds the symbolic entities for schema once, up front.

pub fn schema(&self) -> &Schema

The Schema this symbolic schema was built from.

pub fn sym_env(&self, req_env: &RequestEnv) -> Result<SymEnv>

Returns a SymEnv for req_env, reusing the precomputed [SymEntities].

Only the (cheap) symbolic request is built per call; the (expensive) symbolic entities are shared via a reference-counted clone. The resulting SymEnv is identical to one built by SymEnv::new for the same schema and request environment.
