The extra library definitions available in this Starlark implementation, but not in the standard.

Variants

StructType

Definitions to support the struct type, the struct() constructor.

RecordType

Definitions to support the record type, the record() constructor and field() function.

EnumType

Definitions to support the enum type, the enum() constructor.

Map

A function map(f, xs) which applies f to each element of xs and returns the result.

Filter

A function filter(f, xs) which applies f to each element of xs and returns those for which f returns True. As a special case, filter(None, xs) removes all None values.

Partial

Partially apply a function, partial(f, *args, **kwargs) will create a function where those args kwargs are already applied to f.

Debug

Add a function debug(x) which shows the Rust Debug representation of a value. Useful when debugging, but the output should not be considered stable.

Print

Add a function print(x) which prints to stderr.

Pprint

Add a function pprint(x) which pretty-prints to stderr.

Breakpoint

Add a function breakpoint() which will drop into a console-module evaluation prompt.

Json

Add a function json() which will generate JSON for a module.

Typing

Provides typing.All, typing.Callable etc. Usually used in conjunction with Dialect::enable_types.

Internal

Utilities exposing starlark-rust internals. These are not for production use.

CallStack

Add a function call_stack() which returns a string representation of the current call stack.

Implementations

impl LibraryExtension

pub fn add(self, builder: &mut GlobalsBuilder)

Add a specific extension to a GlobalsBuilder.

Trait Implementations

impl Clone for LibraryExtension

fn clone(&self) -> LibraryExtension

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Dupe for LibraryExtension

fn dupe(&self) -> Self

impl PartialEq for LibraryExtension

fn eq(&self, other: &LibraryExtension) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
