Utilities for working with hierarchical tree-structured data.

Functions

all(tree[, is_leaf])	Check if all leaves in the tree evaluate to True.
field([static, metadata])	Create a field specification with struct-related metadata.
fields(class_or_instance)	Return a tuple describing the fields of this dataclass.
flatten(x[, is_leaf])	Flatten a tree into a list of leaves and a treedef.
is_leaf(x)	Check if a value is a leaf in a tree.
is_struct(obj)	Check if an object is a registered struct class.
leaves(tree[, is_leaf])	Extract all leaf values from a tree.
map(f, tree, *rest[, is_leaf])	Apply a function to each leaf in a tree.
ravel(tree)	Flatten a tree to a single 1D array.
reduce(function, tree, initializer[, is_leaf])	Reduce a tree to a single value using a function and initializer.
register_dataclass(nodetype[, data_fields, ...])	Register a dataclass as tree-compatible with customized field handling.
register_struct(ty, to_iter, from_iter)	Register a custom type as a tree-compatible dataclass.
replace(obj, /, **changes)	Return a new object replacing specified fields with new values.
struct([cls])	Decorator to convert a class into a tree-compatible frozen dataclass.
structure(tree[, is_leaf])	Extract the structure of a tree without the leaf values.
unflatten(treedef, xs)	Reconstruct a tree from a list of leaves and a treedef.

Classes

InitVar(type)
StructConfig()	Base class for creating configuration objects with automatic type discrimination.
UnionConfig()	Discriminated union of StructConfig subclasses.
