Enum ChildOutputDescription 

pub enum ChildOutputDescription {
    Split {
        stdout: Option<ChildSingleOutput>,
        stderr: Option<ChildSingleOutput>,
    },
    Combined {
        output: ChildSingleOutput,
    },
    NotLoaded,
}

The output of a child process during live execution.

This represents either split stdout/stderr or combined output. The Option wrappers distinguish between “not captured” (None) and “captured but empty” (Some with empty content).

The NotLoaded variant is used during replay when the display configuration indicates that output won’t be shown.

For the recording counterpart, see ZipStoreOutputDescription.

Variants

Split

The output was split into stdout and stderr.

Fields

stdout: Option<ChildSingleOutput>

Standard output, or None if not captured.

stderr: Option<ChildSingleOutput>

Standard error, or None if not captured.

Combined

The output was combined into a single stream.

Fields

output: ChildSingleOutput

The combined output.

NotLoaded

Output exists but was not loaded.

This variant is used during replay when the display configuration indicates that output won’t be shown. Code that accesses output bytes must never be reached with this variant.

Implementations
