Source

pub struct UseWebLockOptions { /* private fields */ }

Expand description

Options for crate::use_web_lock_with_options.

Implementations§

Source §

impl UseWebLockOptions

Source

pub fn mode(self, value: LockMode) -> Self

The default mode is LockMode::Exclusive, but LockMode::Shared can be specified. There can be only one Exclusive holder of a lock, but multiple Shared requests can be granted at the same time. This can be used to implement the readers-writer pattern.

Source

pub fn if_available(self, value: bool) -> Self

If true, the lock request will fail if the lock cannot be granted immediately without waiting. The callback is invoked with null. Defaults to false.

Source

pub fn steal(self, value: bool) -> Self

If true, then any held locks with the same name will be released, and the request will be granted, preempting any queued requests for it. Defaults to false.
