Struct Choice 

pub struct Choice { /* private fields */ }

Choice composition - conditional execution

Executes one of two branches based on a predicate function. If the predicate returns true, the if_true branch executes; otherwise, the if_false branch executes (if provided).

Example

let choice = Choice::new(
    |ctx| ctx.get_variable("dry_run").is_some(),
    dry_run_composition,
).with_else(real_execution_composition);

Implementations

impl Choice

pub fn new( predicate: impl Fn(&ExecutionContext) -> bool + Send + Sync + 'static, if_true: impl Composition + 'static, ) -> Self

Creates a new choice composition

Arguments

• predicate - Function that evaluates the context to choose a branch
• if_true - Composition to execute if predicate returns true

pub fn with_else(self, if_false: impl Composition + 'static) -> Self

Adds an else branch to execute if the predicate returns false

Trait Implementations

impl Composition for Choice

fn execute<'life0, 'async_trait>( &'life0 self, ctx: ExecutionContext, ) -> Pin<Box<dyn Future<Output = Result<CompositionResult, ToolError>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Executes the composition with the given context
