Struct ForeignCallResult

pub struct ForeignCallResult<F> {
    pub values: Vec<ForeignCallParam<F>>,
}

Represents the full output of a foreign call.

A foreign call can return multiple outputs, where each output can be either a single field element or an array. This struct wraps a vector of ForeignCallParam to represent all outputs from a single foreign call.

Fields

values: Vec<ForeignCallParam<F>>

Resolved output values of the foreign call.

Each element represents one output, which can be either a single value or an array.

Trait Implementations

impl<F: Clone> Clone for ForeignCallResult<F>

fn clone(&self) -> ForeignCallResult<F>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<F: Debug> Debug for ForeignCallResult<F>

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

Formats the value using the given formatter.

impl<F: Default> Default for ForeignCallResult<F>

fn default() -> ForeignCallResult<F>

Returns the “default value” for a type.

impl<'de, F> Deserialize<'de> for ForeignCallResult<F>

where F: Deserialize<'de>,

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<F> From<F> for ForeignCallResult<F>

Convenience conversion for a foreign call returning a single field element value.

Creates a ForeignCallResult with one output containing the single value.

fn from(value: F) -> Self

Converts to this type from the input type.

impl<F> From<Vec<F>> for ForeignCallResult<F>

Conversion for a foreign call returning a single array output. Creates a ForeignCallResult with one output, where that output is an array. This represents one array output, not multiple single-value outputs:

let result: ForeignCallResult<F> = vec![1, 2, 3].into();
// result.values.len() == 1
// result.values[0] == ForeignCallParam::Array([1, 2, 3])

For multiple single-value outputs, use From<Vec<ForeignCallParam<F>>> instead:

let result: ForeignCallResult<F> = vec![
    ForeignCallParam::Single(1),
    ForeignCallParam::Single(2),
    ForeignCallParam::Single(3)
].into();
// result.values.len() == 3

fn from(values: Vec<F>) -> Self

Converts to this type from the input type.

impl<F> From<Vec<ForeignCallParam<F>>> for ForeignCallResult<F>

Conversion for a foreign call returning multiple outputs.

Each element in the vector represents a separate output, which can be either a single value or an array.

fn from(values: Vec<ForeignCallParam<F>>) -> Self

Converts to this type from the input type.

impl<F: PartialEq> PartialEq for ForeignCallResult<F>

fn eq(&self, other: &ForeignCallResult<F>) -> 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.

impl<F> Serialize for ForeignCallResult<F>

where F: Serialize,

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
