Struct IndexSnapshot 

pub struct IndexSnapshot {
    pub columns: Vec<String>,
    pub unique: bool,
}

Snapshot of a secondary index defined on a table.

Fields

columns: Vec<String>

Names of the columns covered by the index, in index order.

unique: bool

Whether the index enforces uniqueness across the covered columns.

Trait Implementations

impl CandidType for IndexSnapshot

fn _ty() -> Type

fn _ty_doc() -> TypeDoc

fn id() -> TypeId

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

where __S: Serializer,

fn ty() -> Type

impl Clone for IndexSnapshot

fn clone(&self) -> IndexSnapshot

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for IndexSnapshot

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for IndexSnapshot

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Encode for IndexSnapshot

const ALIGNMENT: u16 = 32

The alignment requirement in bytes for the data type.

const SIZE: DataSize = DataSize::Dynamic

The size characteristic of the data type.

fn size(&self) -> u16

Returns the size in bytes of the encoded data type.

fn encode(&self) -> Cow<'_, [u8]>

Encodes the data type into a vector of bytes.

fn decode(data: Cow<'_, [u8]>) -> Result<IndexSnapshot, MemoryError>

where IndexSnapshot: Sized,

Decodes the data type from a slice of bytes.

impl PartialEq for IndexSnapshot

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

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.
