Enum ShellConstructKind 

pub enum ShellConstructKind {
    CommandSubstitution,
    BackquoteSubstitution,
    ArithmeticExpansion,
}

Parse and inspect Brush shell source without expansion or execution.

The returned source-bound schema lets an embedder present command substitutions, state-free arithmetic expansions, redirections, and statically discoverable commands for approval before invoking BrushShellTool. Arithmetic that depends on shell variables, arrays, assignments, or nested expansion fails closed, as do parameter forms that can reinterpret runtime values as expansion syntax. A dynamic construct recognized in a shell word.

Variants

CommandSubstitution

$(...).

BackquoteSubstitution

Legacy backquote substitution.

ArithmeticExpansion

A state-free $((...)) or $[...] expression. Arithmetic that reads or mutates shell state is rejected instead of emitting this projection.
