Struct rdf_types::generator::Blank

pub struct Blank { /* private fields */ }

Generates numbered blank node identifiers, with an optional prefix.

This generator can create usize::MAX unique blank node identifiers. If Generator::next is called usize::MAX + 1 times, it will panic.

Implementations

impl Blank

pub fn new() -> Self

Creates a new numbered generator with no prefix.

pub fn new_with_offset(offset: usize) -> Self

Creates a new numbered generator with no prefix, starting with the given offset number.

The returned generator can create usize::MAX - offset unique blank node identifiers before panicking.

pub fn new_with_prefix(prefix: String) -> Self

Creates a new numbered generator with the given prefix.

pub fn new_full(prefix: String, offset: usize) -> Self

Creates a new numbered generator with the given prefix, starting with the given offset number.

The returned generator can create usize::MAX - offset unique blank node identifiers before panicking.

pub fn prefix(&self) -> &str

Returns the prefix of this generator.

pub fn count(&self) -> usize

Returns the number of already generated identifiers.

pub fn next_blank_id(&mut self) -> BlankIdBuf

Trait Implementations

impl Default for Blank

fn default() -> Blank

Returns the “default value” for a type.

impl<T, B, N: BlankIdVocabularyMut<BlankId = B>> Generator<T, B, N> for Blank

fn next(&mut self, vocabulary: &mut N) -> Subject<T, B>

Generates the next fresh identifier in the given vocabulary.
