Implementations

impl PipelineBuilder

pub fn new() -> Self

Creates a new PipelineBuilder object

pub fn with( &mut self, middleware: fn(&mut dyn PipelineContext, Pipeline) -> Result<(), Box<dyn Error>>, )

Adds a new [MiddlewareThunk] to the pipeline. This can be a free standing fn or an inline closure

pub fn when( &mut self, predicate: fn(&mut dyn PipelineContext) -> bool, builder: fn(&mut PipelineBuilder), )

Branches the Pipeline based on the result of the given [PredicateThunk] with the new set of PipelineBuilder instructions

pub fn assemble(self) -> Pipeline

Assembles the pipeline giving a single entrypoint to pass a PipelineContext in.

The resulting Pipeline object can be cached and run multiple times with different contexts
