Trait ExprEncoding 

pub trait ExprEncoding:
    'static
    + Send
    + Sync
    + Debug
    + Sealed {
    // Required methods
    fn as_any(&self) -> &dyn Any;
    fn id(&self) -> ExprId;
    fn build(
        &self,
        metadata: &[u8],
        children: Vec<ExprRef>,
    ) -> VortexResult<ExprRef>;
}

Encoding trait for a Vortex expression.

An ExprEncoding can be registered with a Vortex session in order to support deserialization via the expression protobuf representation.

Required Methods

fn as_any(&self) -> &dyn Any

fn id(&self) -> ExprId

Returns the ID of the expression encoding.

fn build( &self, metadata: &[u8], children: Vec<ExprRef>, ) -> VortexResult<ExprRef>

Deserializes an expression from its serialized form.

Returns None if the expression is not serializable.

Implementations

impl dyn ExprEncoding + '_

pub fn is<V: VTable>(&self) -> bool

pub fn as_<V: VTable>(&self) -> &V::Encoding

pub fn as_opt<V: VTable>(&self) -> Option<&V::Encoding>

impl Display for dyn ExprEncoding + '_

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

impl Eq for dyn ExprEncoding + '_

impl PartialEq for dyn ExprEncoding + '_

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

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
