Struct rustdb::table::Row

#[non_exhaustive]
pub struct Row {
    pub id: i64,
    pub values: Vec<Value>,
    pub info: Rc<ColInfo>,
    pub codes: Vec<Code>,
}

Row of Values, with type information.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

id: i64

Row Id.

values: Vec<Value>

Row values.

info: Rc<ColInfo>

Type information.

codes: Vec<Code>

Codes for variable length ( binary, string ) values.

Implementations

impl Row

pub fn new(info: Rc<ColInfo>) -> Self

Construct a new row, values are initialised to defaults.

pub fn encode(&mut self, db: &DB)

Calculate codes for current row values.

pub fn delcodes(&self, db: &DB)

Delete current codes.

pub fn load(&mut self, db: &DB, data: &[u8])

Load the row values and codes from data.

Trait Implementations

impl Clone for Row

fn clone(&self) -> Row

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Record for Row

fn save(&self, data: &mut [u8])

Save record as bytes.

fn compare(&self, _db: &DB, data: &[u8]) -> Ordering

Compare record with stored bytes.

fn key(&self, _db: &DB, data: &[u8]) -> Box<dyn Record>

Load key from bytes ( to store in parent page ).

fn drop_key(&self, _db: &DB, _data: &[u8])

Drop parent key ( may need to delete codes ).
