Struct UniqueSet 

pub struct UniqueSet {
    pub columns: Vec<(String, SortOrder)>,
    pub collations: Vec<Option<CollationSeq>>,
    pub is_primary_key: bool,
    pub conflict_clause: Option<ResolveType>,
}

Fields

columns: Vec<(String, SortOrder)>

collations: Vec<Option<CollationSeq>>

Per-column collation overrides from the constraint definition, e.g. PRIMARY KEY(a COLLATE NOCASE). Parallel to columns; None falls back to the column definition’s collation.

is_primary_key: bool

conflict_clause: Option<ResolveType>

Trait Implementations

impl Clone for UniqueSet

fn clone(&self) -> UniqueSet

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for UniqueSet

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

Formats the value using the given formatter.

impl Eq for UniqueSet

impl Hash for UniqueSet

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for UniqueSet

fn cmp(&self, other: &UniqueSet) -> 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 UniqueSet

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

Equality operator ==.

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

Inequality operator !=.

impl PartialOrd for UniqueSet

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