Struct MgpValue 

pub struct MgpValue { /* private fields */ }

Useful to own mgp_value coming from / going into Memgraph as a result.

Underlying pointer object is going to be automatically deleted.

NOTE: Implementing From for MgpValue is not simple because not all Value objects can contain Memgraph object (primitive types).

Makes a copy of the given object returning the MgpValue object. MgpValue objects owns the new object.

pub fn is_vertex(&self) -> bool

pub fn make_edge(edge: &Edge, memgraph: &Memgraph) -> MgpResult<MgpValue>

Makes a copy of the given object returning the MgpValue object. MgpValue objects owns the new object.

pub fn is_edge(&self) -> bool

pub fn make_path(path: &Path, memgraph: &Memgraph) -> MgpResult<MgpValue>

Makes a copy of the given object returning the MgpValue object. MgpValue objects owns the new object.

pub fn is_path(&self) -> bool

Trait Implementations

impl Drop for MgpValue

fn drop(&mut self)
