Struct BindIter 

pub struct BindIter<I> { /* private fields */ }

Wraps an iterator to produce a PG array without allocating an intermediate Vec. Uses size_hint from the iterator for pre-allocation when available.

Example

use pg::{BindIter, ToSql, types::UUID};
let ids: Vec<uuid::Uuid> = vec![/* ... */];
let param = BindIter::new(ids.iter().copied(), &UUID);
conn.execute_raw("SELECT * FROM unnest($1::uuid[])", &[&param]).await?;

Implementations

impl<I> BindIter<I>
