Struct SchemaSystem 

pub struct SchemaSystem { /* private fields */ }

Provides functions for instantiating instances of Schema.

SchemaSystem is Send and Sync i.e. it is safe to send it to another thread and to be shared between threads. For cases when one does need thread-safe interior mutability, they can use the explicit locking via std::sync::Mutex and std::sync::RwLock.

Implementations

impl SchemaSystem

pub fn new(authorities: Vec<Box<dyn DocumentAuthority>>) -> Self

pub fn load_schema<A: AsRef<str>>( &mut self, id: A, ) -> IonSchemaResult<Arc<Schema>>

Requests each of the provided DocumentAuthoritys, in order, to resolve the requested schema id until one successfully resolves it. If an authority throws an exception, resolution silently proceeds to the next authority. This method returns an Arc<Schema> which allows to load this schema once re-use it across threads.

pub fn new_schema( &mut self, schema_content: &[u8], id: &str, ) -> IonSchemaResult<Arc<Schema>>

Constructs a new schema using provided ISL content.

pub fn load_isl_schema<A: AsRef<str>>( &mut self, id: A, ) -> IonSchemaResult<IslSchema>

Requests each of the provided DocumentAuthoritys, in order, to get ISL model for the requested schema id until one successfully resolves it. If an authority throws an exception, resolution silently proceeds to the next authority.

pub fn new_isl_schema( &mut self, schema_content: &[u8], id: &str, ) -> IonSchemaResult<IslSchema>

Constructs a new ISL model using provided ISL content.

pub fn load_schema_from_isl_schema_v1_0( &mut self, isl: IslSchema, ) -> IonSchemaResult<Arc<Schema>>

Resolves given ISL 1.0 model into a Schema. If the given ISL model has any ISL 2.0 related types/constraints, resolution returns an error. This method returns an Arc<Schema> which allows to load this schema once re-use it across threads.

pub fn load_schema_from_isl_schema_v2_0( &mut self, isl: IslSchema, ) -> IonSchemaResult<Arc<Schema>>

Resolves given ISL 2.0 model into a Schema. If the given ISL model has any ISL 1.0 related types/constraints, resolution returns an error. This method returns an Arc<Schema> which allows to load this schema once re-use it across threads.

pub fn schema_from_isl_types_v1_0<A: AsRef<str>, B: Into<Vec<IslType>>>( &self, id: A, isl_types: B, ) -> IonSchemaResult<Schema>

Creates a schema from given IslTypes using ISL 1.0 Note: This method assumes that there are no imported type definitions used for these IslTypes

pub fn schema_from_isl_types_v2_0<A: AsRef<str>, B: Into<Vec<IslType>>>( &self, id: A, isl_types: B, ) -> IonSchemaResult<Schema>

Creates a schema from given IslTypes using ISL 2.0 Note: This method assumes that there are no imported type definitions used for these IslTypes
