Implementations

impl WorkflowSideEffects

pub fn new() -> Self

pub fn shared() -> Arc<Self>

Shared handle.

pub fn set_git_cwd(&self, cwd: impl Into<PathBuf>)

Enable git operations rooted at cwd (must be a git work tree).

pub fn register_template( &self, name: impl Into<String>, body: impl Into<String>, )

Register a named template body. Placeholders use {{key}}.

pub fn write_scratch( &self, name: &str, content: String, ) -> Result<String, HostError>

Write scratch content; returns virtual path scratch/{name}.

Errors

Empty name or oversized content.

pub fn read_scratch(&self, name: &str) -> Result<String, HostError>

Read scratch content.

Errors

Missing file.

pub fn render_template( &self, name: &str, vars: &Value, ) -> Result<String, HostError>

pub fn git_diff_since(&self, commit: &str) -> Result<String, HostError>
