Enum Conflict 

pub enum Conflict<'a, T: IntoIterator<Item: ToSQL<'a, SQLiteValue<'a>>> = Vec<SQL<'a, SQLiteValue<'a>>>> {
    Ignore {
        target: Option<T>,
    },
    Update {
        target: T,
        set: Box<SQL<'a, SQLiteValue<'a>>>,
        target_where: Box<Option<SQL<'a, SQLiteValue<'a>>>>,
        set_where: Box<Option<SQL<'a, SQLiteValue<'a>>>>,
    },
}

Conflict resolution strategies

Variants

Ignore

Do nothing on conflict - ON CONFLICT DO NOTHING

Fields

target: Option<T>

Optional target columns to specify which constraint triggers the conflict

Update

Update on conflict - ON CONFLICT DO UPDATE

Fields

target: T

Target columns that trigger the conflict

set: Box<SQL<'a, SQLiteValue<'a>>>

SET clause for what to update

target_where: Box<Option<SQL<'a, SQLiteValue<'a>>>>

Optional WHERE clause for the conflict target (partial indexes) This goes after the target: ON CONFLICT (col) WHERE condition

set_where: Box<Option<SQL<'a, SQLiteValue<'a>>>>

Optional WHERE clause for the update (conditional updates) This goes after the SET: DO UPDATE SET col = val WHERE condition

Implementations

impl<'a, T> Conflict<'a, T>

where T: IntoIterator<Item: ToSQL<'a, SQLiteValue<'a>>>,

pub fn update<S, TW, SW>( target: T, set: S, target_where: Option<TW>, set_where: Option<SW>, ) -> Self

where S: ToSQL<'a, SQLiteValue<'a>>, TW: ToSQL<'a, SQLiteValue<'a>>, SW: ToSQL<'a, SQLiteValue<'a>>,

Trait Implementations

impl<'a, T: Clone + IntoIterator<Item: ToSQL<'a, SQLiteValue<'a>>>> Clone for Conflict<'a, T>

fn clone(&self) -> Conflict<'a, T>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'a, T: Debug + IntoIterator<Item: ToSQL<'a, SQLiteValue<'a>>>> Debug for Conflict<'a, T>

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

Formats the value using the given formatter.

impl<'a> Default for Conflict<'a>

fn default() -> Self

Returns the “default value” for a type.
