Struct barley_runtime::Context

pub struct Context<'ctx> { /* private fields */ }

A context for running actions.

There should only be one of these per workflow

Implementations

impl<'ctx> Context<'ctx>

pub fn new(callbacks: ContextCallbacks) -> Self

Create a new context with the given callbacks.

If you don’t want any callbacks, it’s recommended to use the Default implementation instead.

pub fn add_action<A: Action + 'ctx>( &mut self, action: A ) -> Arc<dyn Action + 'ctx>

Add an action to the context.

This method adds an action to the context, and returns a reference to the action. The action will be run when the context is run.

You can use the returned reference as a dependency for other actions.

pub async fn run(&mut self) -> Result<()>

Run the context.

While processing the actions, it will call the callbacks if they are set.

pub fn set_variable(&mut self, name: &str, value: &str)

Sets a variable in the context.

This can be used to send information between actions. For example, you could set a return code in one action, and check it in another.

pub fn get_variable(&self, name: &str) -> Option<&str>

Gets a variable from the context.

If the variable doesn’t exist, this method returns None.

Trait Implementations

impl<'ctx> Default for Context<'ctx>

fn default() -> Context<'ctx>

Returns the “default value” for a type.
