Struct NoopContext 

pub struct NoopContext;

No-op context for browser (WASM) execution. All system-access methods return errors — browser has no shell.

Trait Implementations

impl ProcessContext for NoopContext

fn run_command(&self, _cmd: &str, _args: &[&str]) -> Result<Vec<u8>, BntoError>

Run an external command, capturing stdout.

fn temp_file(&self, _suffix: &str) -> Result<PathBuf, BntoError>

Return a unique temporary file path with atomic creation (mkstemp). The file IS pre-created on disk to prevent TOCTOU races.

fn env_var(&self, _key: &str) -> Option<String>

Read an environment variable.

fn work_dir(&self) -> Result<&Path, BntoError>

Get the working directory for this execution.

fn run_command_streaming( &self, cmd: &str, args: &[&str], on_output: &dyn Fn(&str), ) -> Result<Vec<u8>, BntoError>

Run an external command, streaming output lines via a callback.

fn home_dir(&self) -> Option<&Path>

Get the bnto home directory (~/.bnto/ by default). Returns None in browser (WASM) — filesystem paths don’t apply.

fn output_dir(&self) -> Option<PathBuf>

Get the default output directory for recipe results (~/.bnto/output/). Returns None in browser (WASM) — filesystem paths don’t apply.
