Struct SchemaRegistry 

pub struct SchemaRegistry { /* private fields */ }

The schema registry takes care of storing and retrieving table schemas from memory.

Implementations

impl SchemaRegistry

pub fn load() -> MemoryResult<Self>

Load the schema registry from memory.

pub fn register_table<TS>(&mut self) -> MemoryResult<TableRegistryPage>

where TS: TableSchema,

Registers a table and allocates it registry page.

The TableSchema type parameter is used to get the TableSchema::fingerprint of the table schema.

pub fn table_registry_page<TS>(&self) -> Option<TableRegistryPage>

where TS: TableSchema,

Returns the table registry page for a given table schema.

Trait Implementations

impl Clone for SchemaRegistry

fn clone(&self) -> SchemaRegistry

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SchemaRegistry

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

Formats the value using the given formatter.

impl Default for SchemaRegistry

fn default() -> SchemaRegistry

Returns the “default value” for a type.

impl Encode for SchemaRegistry

const SIZE: DataSize = DataSize::Dynamic

fn size(&self) -> MSize

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]>) -> MemoryResult<Self>

where Self: Sized,

Decodes the data type from a slice of bytes.

impl PartialEq for SchemaRegistry

fn eq(&self, other: &SchemaRegistry) -> 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.
