Enum Lock 

pub enum Lock {
    Update,
    Share,
}

A row-level lock to acquire when executing a query.

Corresponds to SQL’s FOR UPDATE and FOR SHARE clauses. Only meaningful for SQL databases that support row-level locking.

Examples

use toasty_core::stmt::Lock;

let lock = Lock::Update;

Variants

Update

FOR UPDATE – acquire an exclusive lock on matched rows.

Share

FOR SHARE – acquire a shared lock on matched rows.

Trait Implementations

impl Clone for Lock

fn clone(&self) -> Lock

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Lock

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

Formats the value using the given formatter.

impl PartialEq for Lock

fn eq(&self, other: &Lock) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
