Enum ConflictTarget 

pub enum ConflictTarget {
    Columns(Vec<String>),
    Constraint(String),
    IndexExpression(String),
    Implicit,
}

What to match on for conflict detection.

Variants

Columns(Vec<String>)

Match on specific columns (unique constraint).

Constraint(String)

Match on a named constraint.

IndexExpression(String)

Match on index expression (PostgreSQL).

Implicit

No specific target (MySQL ON DUPLICATE KEY).

Implementations

impl ConflictTarget

pub fn columns<I, S>(cols: I) -> Self

where I: IntoIterator<Item = S>, S: Into<String>,

Create a column-based conflict target.

pub fn constraint(name: impl Into<String>) -> Self

Create a constraint-based conflict target.

pub fn index_expression(expr: impl Into<String>) -> Self

Create an index expression conflict target.

pub fn to_postgres_sql(&self) -> String

Generate PostgreSQL ON CONFLICT target.

pub fn to_sqlite_sql(&self) -> String

Generate SQLite ON CONFLICT target.

Trait Implementations

impl Clone for ConflictTarget

fn clone(&self) -> ConflictTarget

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ConflictTarget

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ConflictTarget

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for ConflictTarget

fn eq(&self, other: &ConflictTarget) -> 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 Serialize for ConflictTarget

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for ConflictTarget
