Struct tc_table::TableSchema

pub struct TableSchema { /* fields omitted */ }

The schema of a Table.

Implementations

impl TableSchema

pub fn new<I: IntoIterator<Item = (Id, Vec<Id>)>>(
    primary: IndexSchema,
    indices: I
) -> Self

Construct a new Table schema.

pub fn indices(&self) -> &[(Id, Vec<Id>)]

Return a list of index names and the names of the columns they index.

pub fn primary(&self) -> &IndexSchema

Return the IndexSchema of this TableSchema’s primary index.

Trait Implementations

impl CastFrom<TableSchema> for Value

fn cast_from(schema: TableSchema) -> Self

Cast an instance of T into an instance of Self.

impl Clone for TableSchema

fn clone(&self) -> TableSchema

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Display for TableSchema

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

Formats the value using the given formatter.

impl From<IndexSchema> for TableSchema

fn from(schema: IndexSchema) -> TableSchema

Performs the conversion.

impl FromStream for TableSchema

type Context = ()

The decoding context of this type, useful in situations where the stream to be decoded may be too large to hold in main memory.

fn from_stream<'life0, 'async_trait, D: Decoder>(
    cxt: (),
    decoder: &'life0 mut D
) -> Pin<Box<dyn Future<Output = Result<Self, D::Error>> + Send + 'async_trait>> where
    D: 'async_trait,
    'life0: 'async_trait,
    Self: 'async_trait, 

Parse this value using the given Decoder.

impl<'en> IntoStream<'en> for TableSchema

fn into_stream<E: Encoder<'en>>(self, encoder: E) -> Result<E::Ok, E::Error>

Take ownership of this value and serialize it into the given encoder.

impl PartialEq<TableSchema> for TableSchema

fn eq(&self, other: &TableSchema) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &TableSchema) -> bool

This method tests for !=.

impl TryCastFrom<Value> for TableSchema

fn can_cast_from(value: &Value) -> bool

Test if value can be cast into Self.

fn opt_cast_from(value: Value) -> Option<TableSchema>

Returns Some(Self) if the source value can be cast into Self, otherwise None.

fn try_cast_from<Err, OnErr>(value: T, on_err: OnErr) -> Result<Self, Err> where
    OnErr: FnOnce(&T) -> Err, 

Returns Ok(Self) if the source value can be cast into Self, otherwise calls on_err.
