Struct VarPath

Source

pub struct VarPath {
    pub segments: Vec<VarSegment>,
}

Expand description

Variable reference path: ${VAR}, ${VAR[0]}, ${r[key]}, ${a[b][c]}.

The first segment is always the root variable name (Field); the rest are bracket subscripts. $? resolves to the previous command’s exit code as an int (bare only — ${?.field} is rejected). Access is brackets-only: a dotted ${VAR.field} resolves to a loud error suggesting ${VAR[field]}.
