Struct PhysicalColumn 

pub struct PhysicalColumn {
    pub name: ColumnName,
    pub domain: DomainId,
    pub storage: StorageRepr,
    pub nullable: bool,
    pub ordinal: u32,
}

A normalized provider-observed column.

Fields

name: ColumnName

Observed column name.

domain: DomainId

Normalized logical domain.

storage: StorageRepr

Exact provider-boundary representation.

nullable: bool

Observed nullability.

ordinal: u32

Provider ordinal preserving semantic column order.

Trait Implementations

impl Clone for PhysicalColumn

fn clone(&self) -> PhysicalColumn

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PhysicalColumn

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

Formats the value using the given formatter.

impl Eq for PhysicalColumn

impl Ord for PhysicalColumn

fn cmp(&self, other: &PhysicalColumn) -> 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.

fn clamp_to<R>(self, range: R) -> Self

where Self: Sized, R: ClampBounds<Self>,

🔬This is a nightly-only experimental API. (clamp_to)

Restrict a value to a certain range.

impl PartialEq for PhysicalColumn

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

Equality operator ==.

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

Inequality operator !=.

impl PartialOrd for PhysicalColumn

fn partial_cmp(&self, other: &PhysicalColumn) -> 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.
