Struct CommandLineDecorations 

pub struct CommandLineDecorations {
    pub spans: Vec<CommandLineSpan>,
    pub error: Option<String>,
    pub param_hint: Option<String>,
}

Live decorations for the : line (MB.4): syntax spans, an optional validation error, and an optional parameter hint.

Fields

spans: Vec<CommandLineSpan>

Per-token highlight spans over the line text.

error: Option<String>

A live error message (unknown command / bad args), surfaced only once the command word is “committed” (a trailing space or !) so a valid-command prefix mid-typing doesn’t flash red.

param_hint: Option<String>

A parameter hint (<pat>/<rep>/[flags], <file>, …) derived from the resolved command’s ArgSpecs. Shown dim after the line.
