Struct Metadata 

pub struct Metadata { /* private fields */ }

Implementations

impl Metadata

pub fn scan(roots: &[PathBuf]) -> Metadata

pub fn is_loaded(&self) -> bool

False when no metadata was found at all, which has to silence every diagnostic: an unknown attribute and an unknown instance look the same.

pub fn attributes_of( &self, type_id: &str, ) -> Option<&BTreeMap<String, AttributeDefinition>>

pub fn attribute( &self, type_id: &str, attribute_id: &str, ) -> Option<&AttributeDefinition>

pub fn knows(&self, type_id: &str) -> bool

Whether the metadata extends this object type at all. A type it never mentions says nothing about an attribute, so nothing is reported for it.
