Struct PgArray 

pub struct PgArray<T>(pub Vec<T>);

Wrapper for passing a Vec<T> as a single PostgreSQL array parameter.

Without this wrapper, Vec<T> implements ToSQL by joining elements with commas ($1, $2, $3), which is correct for IN (...) clauses but wrong for array operators like @>, <@, and && which expect a single array parameter.

Example

let tags = SQL::<PostgresValue>::raw("tags");
// Correct: passes as a single array parameter
let condition = array_contains(tags, PgArray(vec!["rust", "python"]));

Tuple Fields

0: Vec<T>

Trait Implementations

impl<'a, T> ToSQL<'a, PostgresValue<'a>> for PgArray<T>

where T: Into<PostgresValue<'a>> + Clone,

fn to_sql(&self) -> SQL<'a, PostgresValue<'a>>

fn into_sql(self) -> SQL<'a, V>

where Self: Sized,

Consume self and return SQL without cloning. Default delegates to to_sql() (which clones). Types that own their SQL (like SQL and SQLExpr) override this to avoid the clone.
