Struct Merged 

pub struct Merged<'a> { /* private fields */ }

A context definition viewed together with the definition it pulls in through @import.

The importing definition wins over the imported one for every entry, which is what the specification means by “merging context into import context, replacing common entries”. Reading through this type lets the algorithm treat the pair as one definition without building a merged copy.

Implementations

impl<'a> Merged<'a>

pub fn new(base: &'a Definition, imported: Option<Context>) -> Self

Views base together with the context it imports.

imported is the already-dereferenced @import target, or None when the definition has no @import.

pub fn imported(&self) -> Option<&Definition>

Returns the imported context definition, if there is one.

Yields None when nothing was imported, and also when what was imported is not a single context definition object — a shape the caller has already rejected before reaching here.

pub fn base(&self) -> Option<Nullable<&IriRefBuf>>

Returns the @base entry, falling back to the imported definition’s.

pub fn vocab(&self) -> Option<Nullable<&Vocab>>

Returns the @vocab entry, falling back to the imported definition’s.

pub fn language(&self) -> Option<Nullable<&LenientLangTagBuf>>

Returns the @language entry, falling back to the imported definition’s.

pub fn direction(&self) -> Option<Nullable<Direction>>

Returns the @direction entry, falling back to the imported definition’s.

pub fn protected(&self) -> Option<bool>

Returns the @protected entry, falling back to the imported definition’s.

This is the context-wide default applied to every term it defines, not the flag of an individual term definition.

pub fn type_(&self) -> Option<Type>

Returns the @type entry, falling back to the imported definition’s.

@type is the one keyword a context may redefine, to give it an @set container or mark it protected.

pub fn bindings(&self) -> MergedBindings<'_>

Iterates over every term definition of both definitions, without repeating a term the importing definition overrides.

pub fn get(&self, key: &KeyOrKeyword) -> Option<EntryValueRef<'_>>

Returns the entry bound to key, preferring the importing definition’s.

Trait Implementations

impl<'a> From<&'a Definition> for Merged<'a>

fn from(base: &'a Definition) -> Self

Converts to this type from the input type.
