Struct json_ld::id::generator::Blank

pub struct Blank<M> { /* 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<M> Blank<M>

pub fn new(metadata: M) -> Blank<M>

Creates a new numbered generator with no prefix.

pub fn new_with_offset(metadata: M, offset: usize) -> Blank<M>

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(metadata: M, prefix: String) -> Blank<M>

Creates a new numbered generator with the given prefix.

pub fn new_full(metadata: M, prefix: String, offset: usize) -> Blank<M>

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 metadata(&self) -> &M

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
