Enum BeholderMode 

pub enum BeholderMode {
    Rewriter {
        adjust_argv: fn(&mut Vec<String>),
    },
    DynamicRewriter {
        add_args: Vec<String>,
    },
    Parser,
}

Whether a beholder modifies the invocation (rewriter) or reads human output (parser).

Variants

Rewriter

Rewrites argv before spawn to enable structured output.

Fields

adjust_argv: fn(&mut Vec<String>)

Applied to argv in-place when the beholder attaches.

DynamicRewriter

Rewrites argv by appending a fixed set of args. Used by user-defined drop-in beholders whose add_args are loaded from TOML at runtime.

Fields

add_args: Vec<String>

Args to append when not already present in argv.

Parser

Reads the tool’s human-formatted output without rewriting argv.
