Struct Context

pub struct Context<T> { /* private fields */ }

An evaluation context used to retrieve bindings in test set expressions.

Implementations

impl<T> Context<T>

pub fn new() -> Self

Create a new evaluation context with no bindings.

impl<T> Context<T>

pub fn bind<V: Into<Value<T>>>(&mut self, id: Id, value: V) -> Option<Value<T>>

Inserts a new binding, possibly overriding an old one, returns the old binding if there was one.

pub fn resolve<I: AsRef<str>>(&self, id: I) -> Result<Value<T>, Error>

where T: Clone,

Resolves a binding with the given identifier.

pub fn find_similar(&self, id: &str) -> Vec<Id>

Find similar bindings to the given identifier.

Trait Implementations

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

Performs copy-assignment from source.

impl<T: Debug> Debug for Context<T>

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