Aliases
__copyinit__is_trivial
alias __copyinit__is_trivial
A flag (often compiler generated) to indicate whether the implementation of __copyinit__ is trivial.
The implementation of __copyinit__ is considered to be trivial if:
- The struct has a compiler-generated trivial
__copyinit__and all its fields have a trivial__copyinit__method.
In practice, it means the value can be copied by copying the bits from one location to another without side effects.
__del__is_trivial
alias __del__is_trivial
A flag (often compiler generated) to indicate whether the implementation of __del__ is trivial.
The implementation of __del__ is considered to be trivial if:
- The struct has a compiler-generated trivial destructor and all its fields
have a trivial
__del__method.
In practice, it means that the __del__ can be considered as no-op.
__moveinit__is_trivial
alias __moveinit__is_trivial
A flag (often compiler generated) to indicate whether the implementation of __moveinit__ is trivial.
The implementation of __moveinit__ is considered to be trivial if:
- The struct has a compiler-generated
__moveinit__and all its fields have a trivial__moveinit__method.
In practice, it means the value can be moved by moving the bits from one location to another without side effects.
Methods
__init__
__init__(out self: _Self, obj: PythonObject)
Attempt to construct an instance of this object from a read-only Python value.
Args:
- obj (
PythonObject): The Python object to convert from.
Returns:
_Self
Raises:
If conversion was not successful.
__copyinit__
__copyinit__(out self: _Self, existing: _Self, /)
Create a new instance of the value by copying an existing one.
Args:
- existing (
_Self): The value to copy.
Returns:
_Self
__moveinit__
__moveinit__(out self: _Self, var existing: _Self, /)
Create a new instance of the value by moving the value of another.
Args:
- existing (
_Self): The value to move.
Returns:
_Self
copy
copy(self: _Self) -> _Self
Explicitly construct a copy of self.
Returns:
_Self: A copy of this value.
