Flow functions

Reference documentation for Expressif functions in the flow scope.

Name	Overview
apply	Evaluates an expression with the input value as its current context.
catch	Returns a recovery result and terminates the current pipeline when the input is null; otherwise, passes the input through.
guard	Evaluates an expression only when the current input is directly compatible with its entry contract; otherwise, returns the original input unchanged.
let	Evaluates named bindings once and preserves the pipeline input for subsequent stages.
switch	Returns the result of the first branch whose predicate accepts the original input, or the final fallback, or null.
throw	Raises an evaluation exception when the input is rejected; otherwise, passes the input through.
transform-as	Transforms one or more named expression results with the same open expression and returns them as a record.
transform-with	Transforms the results of one or more expressions with the same open expression and returns them as a tuple.
try	Returns the first candidate result accepted by its predicate, or the final fallback, or null.
