Struct RowData 

pub struct RowData {
    pub sql_type: Arc<SqlTypeDefinition>,
    pub min: TransactionId,
    pub max: Option<TransactionId>,
    pub item_pointer: ItemPointer,
    pub user_data: SqlTuple,
}

Holds information about a particular row in a table as well as metadata.

Fields

sql_type: Arc<SqlTypeDefinition>

Type that defines the row

min: TransactionId

Lowest transaction this row is valid for (still need to check that transaction’s status)

max: Option<TransactionId>

Max transaction this row is valid for OR None for still valid (still need to check max’s status)

item_pointer: ItemPointer

Page + Offset where this row is stored on disk

user_data: SqlTuple

Columns stored in this row

Implementations

impl RowData

pub fn new( sql_type: Arc<SqlTypeDefinition>, min: TransactionId, max: Option<TransactionId>, item_pointer: ItemPointer, user_data: SqlTuple, ) -> RowData

pub fn get_column( &self, name: &str, ) -> Result<Option<BaseSqlTypes>, RowDataError>

pub fn get_column_not_null( &self, name: &str, ) -> Result<BaseSqlTypes, RowDataError>

pub fn parse( table: Arc<Table>, row_buffer: &mut impl Buf, ) -> Result<RowData, RowDataError>

Trait Implementations

impl Clone for RowData

fn clone(&self) -> RowData

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RowData

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

Formats the value using the given formatter.

impl Display for RowData

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

Formats the value using the given formatter.

impl EncodedSize<&SqlTuple> for RowData

fn encoded_size(input: &SqlTuple) -> usize

impl PartialEq for RowData

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