Struct BlankNode

pub struct BlankNode(/* private fields */);

A String wrapper for blank nodes.

Implementations

impl BlankNode

pub fn generate() -> Self

Construct a new blank node with a generated identifier.

pub fn is_valid_str<S>(s: S) -> bool

where S: AsRef<str>,

Returns true if the string is a valid blank node identifier, else false. Note that this function will accept simple names, or those with the reserved prefix "_:".

pub fn to_qname(&self) -> QName

Return a qualified version of the blank node, i.e. with the reserved namespace value "_".
