Struct DryContext 

pub struct DryContext { /* private fields */ }

DryContext contains only serializable data values

Implementations

impl DryContext

pub fn new() -> Self

pub fn with_value<T: Serialize>(self, key: impl Into<String>, value: T) -> Self

pub fn insert<T: Serialize>(&mut self, key: impl Into<String>, value: T)

pub fn get<T: for<'de> Deserialize<'de>>(&self, key: &str) -> Option<T>

pub fn get_required<T: for<'de> Deserialize<'de>>( &self, key: &str, ) -> Result<T, OpError>

pub fn contains(&self, key: &str) -> bool

pub fn keys(&self) -> impl Iterator<Item = &String>

pub fn values(&self) -> &HashMap<String, Value>

pub fn get_or_insert_with<T, F>( &mut self, key: &str, factory: F, ) -> Result<T, OpError>

where T: Serialize + for<'de> Deserialize<'de>, F: FnOnce() -> T,

Get a value or insert it using a factory closure if it doesn’t exist

pub fn get_or_compute_with<T, F>( &mut self, key: &str, computer: F, ) -> Result<T, OpError>

where T: Serialize + for<'de> Deserialize<'de>, F: FnOnce(&mut Self, &str) -> T,

Get a value or compute it using a closure that has access to the context

pub async fn ensure<T, F>( &mut self, key: &str, wet: &mut WetContext, factory: F, ) -> Result<T, OpError>

where T: Serialize + for<'de> Deserialize<'de>, F: for<'a> FnOnce(&'a mut Self, &'a mut WetContext, &'a str) -> Pin<Box<dyn Future<Output = Result<T, OpError>> + Send + 'a>>,

Get a value or compute it using a closure that has access to the context The closure receives mutable access to the context and the key, and must insert the value itself

pub fn merge(&mut self, other: DryContext)

pub fn set_abort(&mut self, reason: Option<String>)

Set abort flag with optional reason

pub fn is_aborted(&self) -> bool

Check if abort flag is set

pub fn abort_reason(&self) -> Option<&String>

Get abort reason if set

pub fn clear_control_flags(&mut self)

Clear all control flags
