Struct json_ld::BlankId

pub struct BlankId(_);

Blank node identifier.

Blank nodes are non-uniquely identified nodes that are local to a JSON-LD document.

{
  "@id": "_:node1",
  "name": "Local blank node 1",
  "knows": {
    "name": "Local blank node 2, that needs to refer to local node 1",
    "knows": { "@id": "_:node1" }
  }
}

This type represent a blank node identifier of the form _:name. It is used by the Reference type to reference blank and non-blank nodes.

Implementations

impl BlankId

pub fn new(name: &str) -> BlankId

Create a new blank identifier from a given name.

The created blank node will be of the form _:name.

pub fn as_str(&self) -> &str

Get the blank identifier as a string.

This includes the _: prefix. Use BlankId::name to get the suffix part only.

pub fn name(&self) -> &str

Get the name/suffix part of the identifier.

For a blank identifier _:name, this returns a string slice to name.
