Struct VowAsync 

pub struct VowAsync<T, F> { /* private fields */ }

Asynchronously binds data to a file.

Implementations

impl<T, F> VowAsync<T, F>

pub fn get(&self) -> &T

Get the value.

impl<T, F> VowAsync<T, F>

where T: Data, F: VowFileAsync,

pub async fn set(&mut self, value: T) -> VowResult<()>

Set the value.

pub async fn map<U>(&mut self, f: U) -> VowResult<()>

where U: FnOnce(T) -> T + MaybeSend,

Map the value.

pub async fn update<U>(&mut self, f: U) -> VowResult<()>

where U: FnOnce(&mut T) + MaybeSend,

Update the value.

pub async fn force_reload(&mut self) -> VowResult<()>

Force reload the value.

pub async fn flush(&mut self) -> VowResult<()>

Flush the content down to disk.

impl<T, F> VowAsync<T, F>

where T: Data, F: VowFileAsync,

pub async fn new(file: F) -> VowResult<Self>

Create a new Vow instance asynchronously with content stored in file.

This will fail if the file contains invalid data.

impl VowAsync<Infallible, File>

pub fn open_tokio<P: AsRef<Path>>( path: P, ) -> VowBuilder<Nothing<Infallible>, File, Async, Json>

Available on crate feature backend-tokio only.

Open a tokio file at the given path.

impl VowAsync<Infallible, File>

pub fn open_async_std<P: AsRef<Path>>( path: P, ) -> VowBuilder<Nothing<Infallible>, File, Async, Json>

Available on crate feature backend-async-std only.

Open an async_std file at the given path.

impl VowAsync<Infallible, File>

pub fn open_compio<P: AsRef<Path>>( path: P, ) -> VowBuilder<Nothing<Infallible>, File, Async, Json>

Available on crate feature backend-compio only.

Open a compio file at the given path.

impl<T, F: VowFileAsync> VowAsync<T, F>

pub const fn builder(file: F) -> VowBuilder<Nothing<T>, F, Async, Json>

where F: VowFileAsync,

Create a new builder for VowAsync.

Trait Implementations

impl<T: Clone, F: Clone> Clone for VowAsync<T, F>

fn clone(&self) -> VowAsync<T, F>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<T: Debug, F: Debug> Debug for VowAsync<T, F>

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

Formats the value using the given formatter.

impl<T, F> Deref for VowAsync<T, F>

type Target = T

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.
