Struct tc_scalar::reference::IfRef

pub struct IfRef { /* private fields */ }

A conditional reference.

Trait Implementations

impl Clone for IfRef

fn clone(&self) -> IfRef

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for IfRef

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

Formats the value using the given formatter.

impl FromStream for IfRef

type Context = ()

The decoding context of this type, useful in situations where the stream to be decoded may be too large to hold in main memory.

fn from_stream<'life0, 'async_trait, D>( context: (), decoder: &'life0 mut D ) -> Pin<Box<dyn Future<Output = Result<Self, D::Error>> + Send + 'async_trait>>

where D: 'async_trait + Decoder, Self: 'async_trait, 'life0: 'async_trait,

Parse this value using the given Decoder.

impl GetSize for IfRef

fn get_heap_size(&self) -> usize

Determines how many bytes this object occupies inside the heap.

fn get_stack_size() -> usize

Determines how may bytes this object occupies inside the stack.

fn get_size(&self) -> usize

Determines the total size of the object.

impl<'a, D: Digest> Hash<D> for &'a IfRef

fn hash(self) -> Output<D>

Compute the SHA-2 hash of this value

impl<'en> IntoStream<'en> for IfRef

fn into_stream<E: Encoder<'en>>(self, encoder: E) -> Result<E::Ok, E::Error>

Take ownership of this value and serialize it into the given encoder.

impl PartialEq for IfRef

fn eq(&self, other: &IfRef) -> bool

This method tests for self and other values to be equal, and is used by ==.

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

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

impl<State> Refer<State> for IfRef

where State: StateInstance + Refer<State> + From<Scalar>, State::Closure: From<(Map<State>, OpDef)> + TryCastFrom<State>, Map<State>: TryFrom<State, Error = TCError>, Value: TryFrom<State, Error = TCError> + TryCastFrom<State>, bool: TryCastFrom<State>,

fn dereference_self(self, path: &TCPathBuf) -> Self

Replace references to “$self” with the given relative path.

fn is_conditional(&self) -> bool

Return true if this is a conditional reference (e.g. If or Case).

fn is_inter_service_write(&self, cluster_path: &[PathSegment]) -> bool

Return true if this references a write operation to a cluster other than the path given.

fn is_ref(&self) -> bool

Return true if this state is a resolvable reference.

fn reference_self(self, path: &TCPathBuf) -> Self

Replace the given relative path with “$self”.

fn requires(&self, deps: &mut HashSet<Id>)

Add the dependency [Id]s of this reference to the given set.

fn resolve<'a, 'async_trait, T>( self, context: &'a Scope<'a, State, T>, txn: &'a State::Txn ) -> Pin<Box<dyn Future<Output = TCResult<State>> + Send + 'async_trait>>

where T: 'async_trait + ToState<State> + Public<State> + Instance, Self: 'async_trait, 'a: 'async_trait,

Resolve this reference with respect to the given context.

impl<'en> ToStream<'en> for IfRef

fn to_stream<E: Encoder<'en>>(&'en self, encoder: E) -> Result<E::Ok, E::Error>

Serialize this value into the given encoder.

impl TryCastFrom<Scalar> for IfRef

fn can_cast_from(scalar: &Scalar) -> bool

Test if value can be cast into Self.

fn opt_cast_from(scalar: Scalar) -> Option<Self>

Returns Some(Self) if the source value can be cast into Self, otherwise None.

fn try_cast_from<Err, OnErr>(value: T, on_err: OnErr) -> Result<Self, Err>

where OnErr: FnOnce(&T) -> Err,

Returns Ok(Self) if the source value can be cast into Self, otherwise calls on_err.
