Implementations

impl Closure

pub fn new(context: Map<State>, op: OpDef) -> Self

Construct a new Closure.

pub fn into_inner(self) -> (Map<State>, OpDef)

Return the context and OpDef which define this Closure.

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

Replace references to $self with the given path.

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

Return true if this Closure may write to service other than where it’s defined

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

Replace references to the given path with $self

pub async fn call(self, txn: &Txn, args: State) -> TCResult<State>

Execute this Closure with the given args

pub async fn call_owned(self, txn: Txn, args: State) -> TCResult<State>

Execute this Closure with an owned Txn and the given args.

Trait Implementations

impl Clone for Closure

fn clone(&self) -> Closure

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Closure

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

Formats the value using the given formatter.

impl Display for Closure

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

Formats the value using the given formatter.

impl From<Closure> for State

fn from(closure: Closure) -> Self

Performs the conversion.

impl From<OpDef> for Closure

fn from(op: OpDef) -> Self

Performs the conversion.

impl FromStream for Closure

type Context = Txn

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>(
    txn: Txn,
    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 TryCastFrom<Scalar> for Closure

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.

impl TryCastFrom<State> for Closure

fn can_cast_from(state: &State) -> bool

Test if value can be cast into Self.

fn opt_cast_from(state: State) -> 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.
