Struct rd_interface::context::Context

pub struct Context { /* fields omitted */ }

A context stores a source endpoint, a process info and other any values during connecting.

Implementations

impl Context

pub fn new() -> Context

new a empty context

pub async fn insert_value_lazy(
    &mut self,
    key: String,
    f: impl Fn() -> BoxFuture<'static, Value> + Send + Sync + 'static
) -> Result<()>

Inserts a key-value pair into the context. Value can be compute later.

pub async fn insert<I: Serialize>(
    &mut self,
    key: String,
    value: I
) -> Result<()>

Inserts a key-value pair into the context.

pub async fn remove<T: DeserializeOwned>(&mut self, key: &str) -> Result<()>

Removes a key from the context

pub async fn get<T: DeserializeOwned>(&self, key: &str) -> Result<T>

Returns a value corresponding to the key.

pub async fn insert_value(&mut self, key: String, value: Value)

Inserts a key-value pair into the context.

pub async fn remove_value(&mut self, key: &str) -> Option<Value>

Removes a key from the context, returning the value at the key if the key was previously in the context.

pub async fn get_value(&self, key: &str) -> Option<Value>

Returns a value corresponding to the key.

pub async fn insert_common<T: CommonField>(
    &mut self,
    value: T::Type
) -> Result<()>

Inserts a key-value pair into the context.

pub async fn get_common<T: CommonField>(&self) -> Result<T::Type>

Returns a value corresponding to the key.

Trait Implementations

impl Debug for Context

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

Formats the value using the given formatter.
