Struct F64NonNegative 

pub struct F64NonNegative(/* private fields */);

Contract type for non-negative f64 values (>= 0.0).

Validates on construction, then can unwrap to stdlib f64 via into_inner().

Implementations

impl F64NonNegative

pub fn new(value: f64) -> Result<Self, ValidationError>

Constructs a non-negative f64 value.

Errors

Returns ValidationError::NotFinite if value is NaN or infinite. Returns ValidationError::FloatNegative if value < 0.0.

pub fn get(&self) -> f64

Gets the wrapped value.

pub fn into_inner(self) -> f64

Unwraps to stdlib f64 (trenchcoat off).

async fn elicit<C: ElicitCommunicator>(communicator: &C) -> 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

Generate a Verus specification proof for this type.

fn creusot_proof() -> TokenStream

Generate a Creusot contract proof for this type.

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

impl JsonSchema for F64NonNegative

fn schema_name() -> Cow<'static, str>

The name of the generated JSON Schema.

fn json_schema(_gen: &mut SchemaGenerator) -> Schema

Generates a JSON Schema for this type.

fn inline_schema() -> bool

fn schema_id() -> Cow<'static, str>

Returns a string that uniquely identifies the schema produced by this type.

impl PartialEq for F64NonNegative

fn eq(&self, other: &F64NonNegative) -> bool

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

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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