Implementations

impl ResidentOpDescriptor

pub fn unit(op_id: u32, out: u32, out_generation: u32) -> Self

Construct a nullary Unit leaf that writes one logical empty tuple.

pub fn scan(op_id: u32, source: u32, source_generation: u32) -> Self

Construct a Scan leaf that binds an existing immutable source slot.

pub fn with_schema_winner(self, head: u32, schema_id: u32) -> Self

pub fn test_status(status: ResidentTerminalStatus) -> Result<Self>

pub fn trace_delta( scan_delta: u32, filter_delta: u32, semantic_guard: Option<(u32, u32)>, ) -> Self

Trait Implementations

impl Clone for ResidentOpDescriptor

fn clone(&self) -> ResidentOpDescriptor

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for ResidentOpDescriptor

impl Debug for ResidentOpDescriptor

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

Formats the value using the given formatter.

impl Default for ResidentOpDescriptor

fn default() -> ResidentOpDescriptor

Returns the “default value” for a type.

impl DeviceRepr for ResidentOpDescriptor

impl Eq for ResidentOpDescriptor

impl PartialEq for ResidentOpDescriptor

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