Enum Context 

pub enum Context {
    One(ContextEntry),
    Many(Vec<ContextEntry>),
}

JSON-LD Context.

Can represent a single context entry, or a list of context entries.

Variants

One(ContextEntry)

A single entry, written on its own.

Many(Vec<ContextEntry>)

Several entries, written as a JSON array.

Implementations

impl Context

pub fn one(context: ContextEntry) -> Self

Creates a new context with a single entry.

pub fn null() -> Self

Creates the null context.

pub fn iri_ref(iri_ref: IriRefBuf) -> Self

Creates a new context with a single IRI-reference entry.

pub fn definition(def: Definition) -> Self

Creates a new context with a single context definition entry.

impl Context

pub fn len(&self) -> usize

Returns the number of entries of this context, which is 1 for a single entry.

pub fn is_empty(&self) -> bool

Checks whether this context has no entry, which only an empty array can.

pub fn as_slice(&self) -> &[ContextEntry]

Returns the entries of this context as a slice.

pub fn is_object(&self) -> bool

Checks whether this context is a single context definition, written as a JSON object.

pub fn is_array(&self) -> bool

Checks whether this context is written as a JSON array.

pub fn traverse(&self) -> Traverse<'_>

Returns a depth-first iterator over this context and every fragment it contains, itself included.

pub fn iter(&self) -> Iter<'_, ContextEntry>

Returns an iterator over the entries of this context, in order.
