Module machine 

Evaluates checked expressions and statements against the app’s state.

Modules

carry 🔒

Which values survive a reload: a state keeps its value when the new program still declares it with the same name and a type whose values are laid out the same way.

place 🔒

Reading and changing places: state, locals, and the fields and list items inside them.

stmt 🔒

Statement execution.

walk 🔒

Stepping through what a for loops over, shared by loop statements and for regions.

Structs

Answer 🔒

Where a file dialog’s answer goes: the state its call bound.

Machine 🔒

RuntimeError

A failure while the app runs, such as dividing by zero, pointing at the code responsible.

Targets 🔒

Where a download’s reports go: the state each of its bindings bound.

Enums

Slot 🔒

A local variable’s storage. A for variable over a place holds where its element lives, so writes through it reach the original list.

Functions

binary 🔒

Applies a binary operator other than && and || to evaluated operands.

item 🔒

length 🔒

list_items 🔒

new_frame 🔒

out_of_range 🔒

position 🔒

A list position from an index value, which must not be negative.

written_value 🔒

The value a download’s report writes, as the interpreter holds it.

Type Aliases

Frame 🔒

Request 🔒

Result 🔒
