Struct Schema 

pub struct Schema {
    pub models: IndexMap<ModelId, Model>,
}

Fields

models: IndexMap<ModelId, Model>

Implementations

impl Schema

pub fn from_macro(models: &[Model]) -> Result<Self>

pub fn field(&self, id: FieldId) -> &Field

Get a field by ID

pub fn variant(&self, id: VariantId) -> &EnumVariant

Get a variant by ID

pub fn models(&self) -> impl Iterator<Item = &Model>

pub fn get_model(&self, id: impl Into<ModelId>) -> Option<&Model>

Try to get a model by ID, returning None if not found.

pub fn model(&self, id: impl Into<ModelId>) -> &Model

Get a model by ID

pub fn resolve<'a>( &'a self, root: &'a Model, projection: &Projection, ) -> Option<Resolved<'a>>

Resolve a projection through the schema, returning either a field or an enum variant.

Starting from the root model, walks through each step of the projection, resolving fields, following relations/embedded types, and recognizing enum variant discriminant access.

Returns None if:

• The projection is empty
• Any step references an invalid field/variant index
• A step tries to project through a primitive type

pub fn resolve_field<'a>( &'a self, root: &'a Model, projection: &Projection, ) -> Option<&'a Field>

Resolve a projection to a field, walking through the schema.

Returns None if the projection is empty, invalid, or resolves to an enum variant rather than a field.

pub fn resolve_field_path<'a>(&'a self, path: &Path) -> Option<&'a Field>

Trait Implementations

impl Debug for Schema

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for Schema

fn default() -> Schema

Returns the “default value” for a type.
