Struct BoxInvocation 

pub struct BoxInvocation<'a> {
    pub program: &'a Path,
    pub args: &'a [String],
    pub cwd: &'a Path,
    pub environment: &'a BTreeMap<String, String>,
    pub stdin: StdioMode,
    pub stdout: StdioMode,
    pub stderr: StdioMode,
}

What would be spawned, once the trust chain has finished and the environment is resolved.

This exists so the decision to spawn and the act of spawning are separable. A test can then assert the exact argument vector, working directory and environment a box would run with — including that no shell is involved — without a process ever starting.

Fields

program: &'a Path

The box’s own interpreter.

args: &'a [String]

Arguments, in the order the release and the caller fixed.

cwd: &'a Path

The working directory, always the box root.

environment: &'a BTreeMap<String, String>

The complete environment the child receives.

stdin: StdioMode

Where standard input comes from.

stdout: StdioMode

Where standard output goes.

stderr: StdioMode

Where standard error goes.
