Struct BlankNodeRef 

pub struct BlankNodeRef<'a> { /* private fields */ }

A borrowed blank node reference for zero-copy operations

This is an optimized version for temporary references that avoids allocations

Implementations

impl<'a> BlankNodeRef<'a>

pub fn new(id: &'a str) -> Result<Self, OxirsError>

Creates a new blank node reference with the given identifier

Arguments

• id - The blank node identifier (with or without _: prefix)

Errors

Returns an error if the ID format is invalid according to RDF specifications

pub fn new_unchecked(id: &'a str) -> Self

Creates a new blank node reference without validation

Safety

The caller must ensure the ID is valid and properly formatted

pub fn id(&self) -> &str

Returns the blank node identifier

pub fn as_str(&self) -> &str

Returns the blank node identifier as a string slice

pub fn unique_id(&self) -> Option<u128>

Returns the internal numerical ID of this blank node if it has been created using numerical ID optimization

pub fn local_id(&self) -> &str

Returns the blank node identifier without the _: prefix

pub fn to_owned(&self) -> BlankNode

Converts to an owned BlankNode

impl<'a> Hash for BlankNodeRef<'a>

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl<'a> Ord for BlankNodeRef<'a>

fn cmp(&self, other: &BlankNodeRef<'a>) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl<'a> PartialEq for BlankNodeRef<'a>

fn eq(&self, other: &BlankNodeRef<'a>) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl<'a> PartialOrd for BlankNodeRef<'a>

fn partial_cmp(&self, other: &BlankNodeRef<'a>) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.
