Struct StrStartsSparqlOp 

pub struct StrStartsSparqlOp;

Implementation of the SPARQL strstarts function.

Implementations

impl StrStartsSparqlOp

pub fn new() -> StrStartsSparqlOp

Creates a new StrStartsSparqlOp.

Trait Implementations

impl Debug for StrStartsSparqlOp

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl Default for StrStartsSparqlOp

fn default() -> StrStartsSparqlOp

Returns the “default value” for a type.

impl Hash for StrStartsSparqlOp

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

where __H: Hasher,

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 PartialEq for StrStartsSparqlOp

fn eq(&self, other: &StrStartsSparqlOp) -> 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.
