Struct PythonOptionsDsl 

pub struct PythonOptionsDsl {
    pub scan_fn: Option<PythonObject>,
    pub schema_fn: Option<SpecialEq<Arc<Either<PythonObject, Arc<Schema<DataType>>>>>>,
    pub python_source: PythonScanSource,
    pub validate_schema: bool,
    pub is_pure: bool,
}

Fields

scan_fn: Option<PythonObject>

A function that returns a Python Generator. The generator should produce Polars DataFrame’s.

schema_fn: Option<SpecialEq<Arc<Either<PythonObject, Arc<Schema<DataType>>>>>>

Either the schema fn or schema is set.

python_source: PythonScanSource

validate_schema: bool

is_pure: bool

Implementations

impl PythonOptionsDsl

pub fn get_schema(&self) -> Result<Arc<Schema<DataType>>, PolarsError>

Trait Implementations

impl Clone for PythonOptionsDsl

fn clone(&self) -> PythonOptionsDsl

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for PythonOptionsDsl

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl Default for PythonOptionsDsl

fn default() -> PythonOptionsDsl

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for PythonOptionsDsl

fn deserialize<__D>( __deserializer: __D, ) -> Result<PythonOptionsDsl, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for PythonOptionsDsl

fn eq(&self, other: &PythonOptionsDsl) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for PythonOptionsDsl

fn serialize<__S>( &self, __serializer: __S, ) -> Result<<__S as Serializer>::Ok, <__S as Serializer>::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
