Implementations

impl TablePolicy

pub fn to_json(&self) -> Result<String, String>

TablePolicy 객체를 JSON 문자열로 직렬화하여 Arrow Schema 메타데이터에 심을 수 있게 합니다.

pub fn from_json(json: &str) -> Result<Self, String>

JSON 문자열을 TablePolicy 객체로 역직렬화 합니다.

Trait Implementations

impl Clone for TablePolicy

fn clone(&self) -> TablePolicy

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TablePolicy

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

Formats the value using the given formatter.

impl Default for TablePolicy

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for TablePolicy

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for TablePolicy

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
