Contexts

class unit.Context

Manages state and memory for all UNIT objects. Procedures created with a context share its memory allocator.

Context supports the context manager protocol. When used with with, it becomes the current context, so procedures can be created without passing it explicitly.

Example

# Explicit context
ctx = unit.Context()
proc = unit.Procedure("main", context=ctx)

# Implicit via context manager
with unit.Context():
    proc = unit.Procedure("main")  # uses the current context

__enter__() → Context

Set this context as the current context.

__exit__(*args) → None

Restore the previous context.

classmethod current() → Context | None

Return the current context set by a with block, or None if no context is active.

classmethod current_or_new() → Context

Return the current context if one is active, otherwise create and return a new one. This is what Procedure calls internally when no context is provided.
