Struct UniqueClaim 

pub struct UniqueClaim {
    pub value: Vec<u8>,
    pub order: ClaimOrder,
}

One unique value and the latest claim order of its current input setters.

Fields

value: Vec<u8>

Canonical equality encoding of the whole value: text compares by bytes, since unique index terms are BINARY (§9.2). Non-conflicting nulls make no claim.

order: ClaimOrder

The latest winning setter of any of the constraint’s columns (§9.2).

Trait Implementations

impl Clone for UniqueClaim

fn clone(&self) -> UniqueClaim

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for UniqueClaim

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

Formats the value using the given formatter.

impl PartialEq for UniqueClaim

fn eq(&self, other: &UniqueClaim) -> 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.
