Struct postgres::types::Slice

pub struct Slice<'a, T: 'a + ToSql>(pub &'a [T]);

An adapter type mapping slices to Postgres arrays.

Slice's ToSql implementation maps the slice to a one-dimensional Postgres array of the relevant type. This is particularly useful with the ANY function to match a column against multiple values without having to dynamically construct the query string.

Examples

let values = &[1i32, 2, 3, 4, 5, 6];
let stmt = try!(conn.prepare("SELECT * FROM foo WHERE id = ANY($1)"));
for row in &try!(stmt.query(&[&Slice(values)])) {
    // ...
}
