Trait Implementations

impl Clone for NuLazyFrameCustomValue

fn clone(&self) -> NuLazyFrameCustomValue

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl CustomValue for NuLazyFrameCustomValue

fn clone_value(&self, span: Span) -> Value

Custom Clone implementation

fn type_name(&self) -> String

The friendly type name to show for the custom value, e.g. in describe and in error messages. This does not have to be the same as the name of the struct or enum, but conventionally often is.

fn to_base_value(&self, span: Span) -> Result<Value, ShellError>

Converts the custom value to a base nushell value.

fn as_mut_any(&mut self) -> &mut dyn Any

Any representation used to downcast object to its original type (mutable reference)

fn as_any(&self) -> &dyn Any

Any representation used to downcast object to its original type

fn notify_plugin_on_drop(&self) -> bool

For custom values in plugins: return true here if you would like to be notified when all copies of this custom value are dropped in the engine.

fn follow_path_int( &self, self_span: Span, index: usize, path_span: Span, optional: bool, ) -> Result<Value, ShellError>

Follow cell path by numeric index (e.g. rows).

fn follow_path_string( &self, self_span: Span, column_name: String, path_span: Span, optional: bool, casing: Casing, ) -> Result<Value, ShellError>

Follow cell path by string key (e.g. columns).

fn partial_cmp(&self, _other: &Value) -> Option<Ordering>

ordering with other value (see std::cmp::PartialOrd)

fn operation( &self, lhs_span: Span, operator: Operator, op: Span, right: &Value, ) -> Result<Value, ShellError>

Definition of an operation between the object that implements the trait and another Value.

fn save( &self, path: Spanned<&Path>, value_span: Span, save_span: Span, ) -> Result<(), ShellError>

Save custom value to disk.

fn memory_size(&self) -> usize

Returns an estimate of the memory size used by this CustomValue in bytes

fn is_iterable(&self) -> bool

Returns true if this custom value should be iterable (like a list) when used with commands like each, where, etc.

impl Debug for NuLazyFrameCustomValue

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for NuLazyFrameCustomValue

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PolarsPluginCustomValue for NuLazyFrameCustomValue

type PolarsPluginObjectType = NuLazyFrame

fn custom_value_to_base_value( &self, plugin: &PolarsPlugin, _engine: &EngineInterface, ) -> Result<Value, ShellError>

fn id(&self) -> &Uuid

fn internal(&self) -> &Option<Self::PolarsPluginObjectType>

fn custom_value_partial_cmp( &self, plugin: &PolarsPlugin, _engine: &EngineInterface, other_value: Value, ) -> Result<Option<Ordering>, ShellError>

fn custom_value_operation( &self, plugin: &PolarsPlugin, engine: &EngineInterface, lhs_span: Span, operator: Spanned<Operator>, right: Value, ) -> Result<Value, ShellError>

fn custom_value_follow_path_int( &self, plugin: &PolarsPlugin, engine: &EngineInterface, _self_span: Span, index: Spanned<usize>, ) -> Result<Value, ShellError>

fn custom_value_follow_path_string( &self, plugin: &PolarsPlugin, engine: &EngineInterface, _self_span: Span, column_name: Spanned<String>, ) -> Result<Value, ShellError>

impl Serialize for NuLazyFrameCustomValue

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
