pyarrow.Int8Scalar#

classpyarrow.Int8Scalar#

Bases:Scalar

Concrete class for int8 scalars.

__init__(*args,**kwargs)#

Methods

__init__(*args, **kwargs)
as_py(self, *[, maps_as_pydicts])	Return this value as a Python int.
cast(self[, target_type, safe, options, ...])	Cast scalar value to another data type.
equals(self, Scalar other)
validate(self, *[, full])	Perform validation checks.

Attributes

is_valid	Holds a valid (non-null) value.
type	Data type of the Scalar object.

as_py(self,*,maps_as_pydicts=None)#

Return this value as a Python int.

Parameters:

maps_as_pydictsstr, optional, defaultNone

Valid values areNone, ‘lossy’, or ‘strict’.This parameter is ignored for non-nested Scalars.

cast(self,target_type=None,safe=None,options=None,memory_pool=None)#

Cast scalar value to another data type.

Seepyarrow.compute.cast() for usage.

Parameters:

target_typeDataType, defaultNone

Type to cast scalar to.

safebool, defaultTrue

Whether to check for conversion errors such as overflow.

optionsCastOptions, defaultNone

Additional checks pass by CastOptions

memory_poolMemoryPool, optional

memory pool to use for allocations during function execution.

Returns:

scalarAScalar ofthegiventargetdata type.

equals(self,Scalarother)#

Parameters:

otherpyarrow.Scalar

Returns:

bool

is_valid#

Holds a valid (non-null) value.

type#

Data type of the Scalar object.

validate(self,*,full=False)#

Perform validation checks. An exception is raised if validation fails.

By default only cheap validation checks are run. Passfull=Truefor thorough validation checks (potentially O(n)).

Parameters:

fullbool, defaultFalse

If True, run expensive checks, otherwise cheap checks only.

Raises:

ArrowInvalid
