Struct PioScenarioSet 

pub struct PioScenarioSet { /* private fields */ }

A dynamically typed scenario set at the universal parser boundary. Typed Rust code uses ScenarioSet<T> directly.

Implementations

impl PioScenarioSet

pub fn from_scenarios(scenarios: Vec<Scenario<PioValue>>) -> Result<Self, Error>

Construct the dynamic form from scenarios that already crossed the universal parser boundary.

Typed Rust code should use ScenarioSet<T> and its ordinary From conversion. An empty input has no value from which to infer T and is rejected.

pub fn element_type(&self) -> &str

pub fn type_name(&self) -> &str

pub fn get(&self, id: &str) -> Option<&PioValue>

pub fn get_mut(&mut self, id: &str) -> Option<&mut PioValue>

Mutably borrow one entry by scenario ID through copy on write.

pub fn get_at(&self, position: usize) -> Option<&PioValue>

pub fn get_at_mut(&mut self, position: usize) -> Option<&mut PioValue>

Mutably borrow one entry by insertion position through copy on write.

pub fn iter(&self) -> impl ExactSizeIterator<Item = &Scenario<PioValue>>

pub fn iter_mut( &mut self, ) -> impl ExactSizeIterator<Item = &mut Scenario<PioValue>>

Iterate over mutable scenario entries through one copy on write split.

pub fn len(&self) -> usize

pub fn is_empty(&self) -> bool
