Struct IoPolicy 

pub struct IoPolicy {
    pub stdout: Stream,
    pub stderr: Stream,
}

How a child process’s output streams are handled.

Fields

stdout: Stream

Handling for standard output.

stderr: Stream

Handling for standard error.

Implementations

impl IoPolicy

pub const SILENT: Self

Capture everything - used for build steps, whose output is only interesting when they fail.

pub const ANSWER: Self

Capture standard output but let standard error through live - used for the solution itself, whose stdout carries the answers and whose stderr carries progress the user should see as it happens.

pub const INHERIT: Self

Pass both streams through - used for scaffolding commands.
