Struct BTreeSetNonEmpty 

pub struct BTreeSetNonEmpty<T>(/* private fields */);

A BTreeSet that is guaranteed to be non-empty.

Implementations

impl<T> BTreeSetNonEmpty<T>

pub fn new(set: BTreeSet<T>) -> Result<Self, ValidationError>

Create a new BTreeSetNonEmpty, validating the set is non-empty.

pub fn get(&self) -> &BTreeSet<T>

Get the inner BTreeSet.

pub fn into_inner(self) -> BTreeSet<T>

Unwrap into the inner BTreeSet.

pub fn len(&self) -> usize

Get the length (always >= 1).

pub fn is_empty(&self) -> bool

Check if empty (always returns false for NonEmpty collections).

Trait Implementations

impl<T: Clone> Clone for BTreeSetNonEmpty<T>

fn clone(&self) -> BTreeSetNonEmpty<T>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<T: Debug> Debug for BTreeSetNonEmpty<T>

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

Return the complete assembled prompts in elicitation order.

impl ElicitSpec for BTreeSetNonEmpty<i32>

fn type_spec() -> TypeSpec

Returns the complete spec for this type.

impl<T> Elicitation for BTreeSetNonEmpty<T>

where T: Elicitation + Ord + Send,

type Style = <BTreeSet<T> as Elicitation>::Style

The style enum for this type.

async fn elicit<Comm: ElicitCommunicator>( communicator: &Comm, ) -> ElicitResult<Self>

Elicit a value of this type from the user via style-aware client.

fn kani_proof() -> TokenStream

Generate a Kani symbolic execution proof harness for this type.

fn verus_proof() -> TokenStream

Returns a proc_macro2::TokenStream containing a Verus-verified function with requires/ensures specifications for this type’s invariants.

fn creusot_proof() -> TokenStream

Returns a proc_macro2::TokenStream containing Creusot contract functions with #[requires]/#[ensures]/#[trusted] attributes for this type’s invariants.

fn elicit_checked( peer: Peer<RoleServer>, ) -> impl Future<Output = ElicitResult<Self>> + Send

Server-side elicitation via MCP peer.

fn with_style(style: Self::Style) -> ElicitBuilder<Self>

Create a builder for one-off style override.

fn elicit_proven<C: ElicitCommunicator>( communicator: &C, ) -> impl Future<Output = ElicitResult<(Self, Established<Is<Self>>)>> + Send

fn prusti_proof() -> TokenStream

Returns a proc_macro2::TokenStream containing Prusti contract functions with #[requires]/#[ensures] attributes for this type’s invariants.

impl<T: PartialEq> PartialEq for BTreeSetNonEmpty<T>

fn eq(&self, other: &BTreeSetNonEmpty<T>) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
