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: DialectTypes

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

§enable_f_strings: bool

Are f"{expression}" strings supported? Disabled in all dialects by default.

§_non_exhaustive: ()

Like #[non_exhaustive], but allows struct expression.

Explanation.

Implementations§

source§

impl Dialect

source

pub const Standard: Dialect = _

Follow the Starlark language standard as much as possible.

This is also returned by Dialect::default().

source

pub const Extended: Dialect = _

A superset of Standard, including extra features (types, top-level statements etc).
