dtype

Helper functions for validation of dtype.

For literal dtypes intended for use by end-users, see numpydantic.dtype

validate_dtype(dtype: Any, target: str | type | Any | generic) → bool

Validate a dtype against the target dtype.

If dtype or target are Any, validation passes trivially. The dtype may be Any when the dtype can’t be determined, but failure to determine dtype shouldn’t be fatal (e.g. BaseModel dtypes for empty arrays).

Parameters:

• dtype – The dtype to validate

• target (DtypeType) – The target dtype

Returns:

True if valid, False otherwise

Return type:

bool

is_union(dtype: str | type | Any | generic) → bool

Check if a dtype is a union
