Trait ScriptIo 

pub trait ScriptIo: Send + Sync {
    // Required methods
    fn http_get(
        &self,
        url: &str,
        headers: BTreeMap<String, String>,

    fn env_var(&self, name: &str) -> Result<String, String>;
}

The raw I/O a DaemonScriptHost performs, behind a seam so the host’s permission/confinement logic is testable without real side effects.

Required Methods

fn http_get( &self, url: &str, headers: BTreeMap<String, String>, ) -> Result<String, String>

Perform an HTTP GET, returning the response body (or an error message).

fn http_post( &self, url: &str, body: &str, headers: BTreeMap<String, String>, ) -> Result<String, String>

Perform an HTTP POST, returning the response body (or an error message).

fn run_shell( &self, cmd: TokioCommand, timeout: Duration, ) -> Result<String, String>

Run a prepared shell command (already sandbox-wrapped and pointed at the workdir by the host), enforcing timeout, and return its combined output.

fn read_file(&self, path: &Path) -> Result<String, String>

Read the file at an already-confined absolute path.

fn write_file(&self, path: &Path, content: &str) -> Result<String, String>

Write content to an already-confined absolute path, creating parent directories as needed. Returns a short confirmation.

fn env_var(&self, name: &str) -> Result<String, String>

Read environment variable name.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
