Struct XMap 

pub struct XMap {
    pub task: Signature,
    pub argsets: Vec<Vec<Value>>,
    pub fail_fast: bool,
}

XMap: Map with exception handling

Like Map, but continues processing even if some tasks fail. Failed tasks are tracked separately.

Fields

task: Signature

Task to apply

argsets: Vec<Vec<Value>>

List of argument sets

fail_fast: bool

Whether to stop on first error

Implementations

impl XMap

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

Create a new XMap workflow

pub fn fail_fast(self, fail_fast: bool) -> XMap

Set fail-fast behavior (stop on first error)

pub fn is_empty(&self) -> bool

Check if empty

pub fn len(&self) -> usize

Get number of argument sets

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

where B: Broker,

Apply the xmap by creating a group of tasks

Note: Exception handling is done at the result collection level, not during task submission.

Trait Implementations

impl Clone for XMap

fn clone(&self) -> XMap

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for XMap

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for XMap

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for XMap

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

Formats the value using the given formatter.

impl PartialEq for XMap

fn eq(&self, other: &XMap) -> 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 XMap

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.
