Trait Implementations

impl Clone for Case

fn clone(&self) -> Case

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Case

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

Formats the value using the given formatter.

impl Display for Case

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

Formats the value using the given formatter.

impl FromStream for Case

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

Parse this value using the given Decoder.

impl<'en> IntoStream<'en> for Case

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<Case> for Case

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

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

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

This method tests for !=.

impl Refer for Case

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

Replace the given relative path with “$self”.

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

Add the dependency Ids of this reference to the given set.

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

Resolve this reference with respect to the given context.

impl<'en> ToStream<'en> for Case

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 Case

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.
