Implementations

impl VarValAddr

pub fn new(dt: &DataType, v: &Value, ps: &mut PageSet) -> Self

pub fn get(&self, dt: &DataType, ps: &mut PageSet) -> Value

pub fn update(&self, dt: &DataType, v: &Value, ps: &mut PageSet) -> Self

Trait Implementations

impl Clone for VarValAddr

fn clone(&self) -> VarValAddr

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for VarValAddr

impl Debug for VarValAddr

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

Formats the value using the given formatter.

impl Eq for VarValAddr

impl<'a> Key<VarValAddr> for IdKey<'a>

fn ok(&self, addr: VarValAddr, ps: &mut PageSet) -> Option<(VarValAddr, Value)>

Check that hash lookup has found correct value.

impl Ord for VarValAddr

fn cmp(&self, other: &VarValAddr) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for VarValAddr

fn eq(&self, other: &VarValAddr) -> 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 PartialOrd for VarValAddr

fn partial_cmp(&self, other: &VarValAddr) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl SmallFixed for VarValAddr

fn size() -> usize

fn load(bytes: &[u8]) -> Self

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