Struct Map 

pub struct Map {
    pub task: Signature,
    pub argsets: Vec<Vec<Value>>,
}

Map: Apply task to multiple arguments

map(task, [args1, args2, args3]) -> [result1, result2, result3]

Fields

task: Signature

Task to apply

argsets: Vec<Vec<Value>>

List of argument sets

Implementations

impl Map

pub fn new(task: Signature, argsets: Vec<Vec<Value>>) -> Map

pub async fn apply<B>(self, broker: &B) -> Result<Uuid, CanvasError>

where B: Broker,

Apply the map by creating a group of tasks with different arguments

pub fn is_empty(&self) -> bool

Check if map is empty

pub fn len(&self) -> usize

Get number of argument sets (and thus tasks)

Trait Implementations

impl Clone for Map

fn clone(&self) -> Map

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Map

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Map

fn deserialize<__D>( __deserializer: __D, ) -> Result<Map, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for Map

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

Formats the value using the given formatter.

impl PartialEq for Map

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

impl Serialize for Map

fn serialize<__S>( &self, __serializer: __S, ) -> Result<<__S as Serializer>::Ok, <__S as Serializer>::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
