Expand description

Starlark language features to enable, e.g. Standard to follow the Starlark standard.

Fields

enable_def: bool

Are def statements permitted. Enabled in both Standard and Extended.

enable_lambda: bool

Are lambda expressions permitted. Enabled in both Standard and Extended.

enable_load: bool

Are load statements permitted. Enabled in both Standard and Extended.

enable_keyword_only_arguments: bool

Are * keyword-only arguments allowed as per PEP 3102. Only enabled in Extended.

enable_types: bool

Are expressions allowed in type positions as per PEP 484. Only enabled in Extended.

enable_tabs: bool

Are tabs permitted for indentation. If permitted, tabs are equivalent to 8 spaces. Enabled in both Standard and Extended.

enable_load_reexport: bool

Do load() statements reexport their definition. Enabled in both Standard and Extended, but may change in future definitions of the standard.

enable_top_level_stmt: bool

Are for, if and other statements allowed at the top level. Only enabled in Extended.

Implementations

impl Dialect

pub const Standard: Self

Follow the Starlark language standard as much as possible.

pub const Extended: Self
