Struct Context 

pub struct Context { /* private fields */ }

Execution state shared by a chain of tasks and their nested calls.

A context is synchronous and confined to its caller. No global current directory or environment changes are needed for task execution.

Implementations

impl Context

pub fn root(&self) -> &Path

pub fn previous(&self) -> &Value

pub fn write_output(&mut self, output: &str)

Add user-facing output to the command result. Task diagnostics should use stderr.

pub fn insert<State: Any>(&mut self, state: State)

pub fn get<State: Any>(&self) -> Option<&State>

pub fn get_mut<State: Any>(&mut self) -> Option<&mut State>

pub fn command(&self, program: impl AsRef<OsStr>) -> Command

Start a process in the project root. Arguments go directly to the process; shell parsing is only used if a task explicitly invokes a shell.

pub fn call(&mut self, name: &str, arguments: &[&str]) -> Result<Value>

Invoke one registered task and store its successful output as previous. Explicit calls support composition and project-defined hooks.

pub fn call_if_registered( &mut self, name: &str, arguments: &[&str], ) -> Result<Option<Value>>

Invoke a registered task if it exists, returning None when it is absent. Errors from a registered task are returned unchanged.
