Enum OnInsert

#[non_exhaustive]
pub enum OnInsert {
    DuplicateKeyUpdate(Vec<Assignment>),
}

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

DuplicateKeyUpdate(Vec<Assignment>)

ON DUPLICATE KEY UPDATE (MySQL when the key already exists, then execute an update instead)

Trait Implementations

impl Clone for OnInsert

fn clone(&self) -> OnInsert

Returns a duplicate of the value.

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

Performs copy-assignment from source.

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

Formats the value using the given formatter.

impl Display for OnInsert

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

Formats the value using the given formatter.

impl Hash for OnInsert

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,

impl PartialEq for OnInsert

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