Trait Implementations

impl<'i, D: Clone + Dialect> Clone for ColumnSchema<'i, D>

fn clone(&self) -> ColumnSchema<'i, D>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'i, D: Debug + Dialect> Debug for ColumnSchema<'i, D>

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

Formats the value using the given formatter.

impl<D: Dialect> Display for ColumnSchema<'_, D>

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

Formats the value using the given formatter.

impl<'i, D: Dialect, C: Into<Column<'i>>, T: Into<ColumnType<D>>> From<(C, T)> for ColumnSchema<'i, D>

fn from((name, type): (C, T)) -> ColumnSchema<'i, D>

Converts to this type from the input type.

impl<'i, D: Ord + Dialect> Ord for ColumnSchema<'i, D>

fn cmp(&self, other: &ColumnSchema<'i, D>) -> 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<'i, D: PartialEq + Dialect> PartialEq for ColumnSchema<'i, D>

fn eq(&self, other: &ColumnSchema<'i, D>) -> 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<'i, D: PartialOrd + Dialect> PartialOrd for ColumnSchema<'i, D>

fn partial_cmp(&self, other: &ColumnSchema<'i, D>) -> 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.
