Trait Implementations

impl Clone for Column

fn clone(&self) -> Column

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Column

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

Formats the value using the given formatter.

impl Default for Column

fn default() -> Column

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Column

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for Column

fn eq(&self, other: &Column) -> 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 Column

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl WithMetadata for Column

fn get_metadata(&self) -> &HashMap<String, String>

Borrow metadata container for reading

fn get_metadata_mut(&mut self) -> &mut HashMap<String, String>

Borrow metadata container for writing

fn set_meta( &mut self, meta_key: impl ToString, meta_value: impl ToString, ) -> &mut Self

Set metadata key value pair

fn set_meta_flag(&mut self, meta_flag: impl ToString) -> &mut Self

Set metadata flag

fn meta_flag(&self, flag: &str) -> bool

Check if metadata flag is set

fn meta(&self, key: &str) -> Option<String>

Get metadata value by key
