Struct ExecResult 

#[non_exhaustive]
pub struct ExecResult {
    pub rows_affected: u64,
    pub last_insert_id: Option<i64>,
}

What a side-effect statement reports back.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

rows_affected: u64

How many rows the statement changed.

last_insert_id: Option<i64>

The auto-increment id of the inserted row — MySQL and SQLite only. PostgreSQL answers None: use RETURNING there, which is the honest cross-engine story rather than a pretend-portable one.

Implementations

impl ExecResult

pub fn new(rows_affected: u64, last_insert_id: Option<i64>) -> Self

Assemble a result. Backend-facing (the struct is #[non_exhaustive]).
