Struct casper_types::runtime_args::RuntimeArgs

pub struct RuntimeArgs(_);

Represents a collection of arguments passed to a smart contract.

Implementations

impl RuntimeArgs

pub fn new() -> RuntimeArgs

Create an empty RuntimeArgs instance.

pub fn try_new<F>(func: F) -> Result<RuntimeArgs, CLValueError> where
    F: FnOnce(&mut RuntimeArgs) -> Result<(), CLValueError>, 

A wrapper that lets you easily and safely create runtime arguments.

This method is useful when you have to construct a RuntimeArgs with multiple entries, but error handling at given call site would require to have a match statement for each RuntimeArgs::insert call. With this method you can use ? operator inside the closure and then handle single result. When try_block will be stabilized this method could be deprecated in favor of using those blocks.

pub fn get(&self, name: &str) -> Option<&CLValue>

Gets an argument by its name.

pub fn len(&self) -> usize

Get length of the collection.

pub fn is_empty(&self) -> bool

Check if collection of arguments is empty.

pub fn insert<K, V>(&mut self, key: K, value: V) -> Result<(), CLValueError> where
    K: Into<String>,
    V: CLTyped + ToBytes, 

Insert new named argument into the collection.

pub fn insert_cl_value<K>(&mut self, key: K, cl_value: CLValue) where
    K: Into<String>, 

Insert new named argument into the collection.

pub fn to_values(&self) -> Vec<&CLValue>

Returns values held regardless of the variant.

Trait Implementations

impl Clone for RuntimeArgs

fn clone(&self) -> RuntimeArgs

Returns a copy of the value.

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

Performs copy-assignment from source.

impl DataSize for RuntimeArgs

const IS_DYNAMIC: bool

If true, the type has a heap size that can vary at runtime, depending on the actual value.

const STATIC_HEAP_SIZE: usize

The amount of space a value of the type always occupies. If IS_DYNAMIC is false, this is the total amount of heap memory occupied by the value. Otherwise this is a lower bound.

fn estimate_heap_size(&self) -> usize

Estimates the size of heap memory taken up by this value.

impl Debug for RuntimeArgs

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

Formats the value using the given formatter.

impl Default for RuntimeArgs

fn default() -> RuntimeArgs

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for RuntimeArgs

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error> where
    __D: Deserializer<'de>, 

Deserialize this value from the given Serde deserializer.

impl Eq for RuntimeArgs

impl From<BTreeMap<String, CLValue>> for RuntimeArgs

fn from(cl_values: BTreeMap<String, CLValue>) -> RuntimeArgs

Performs the conversion.

impl From<Vec<NamedArg, Global>> for RuntimeArgs

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

Performs the conversion.

impl FromBytes for RuntimeArgs

fn from_bytes(bytes: &[u8]) -> Result<(Self, &[u8]), Error>

Deserializes the slice into Self.

fn from_vec(bytes: Vec<u8>) -> Result<(Self, Vec<u8>), Error>

Deserializes the Vec<u8> into Self.

impl Hash for RuntimeArgs

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

pub fn hash_slice<H>(data: &[Self], state: &mut H) where
    H: Hasher, 

Feeds a slice of this type into the given Hasher.

impl Into<BTreeMap<String, CLValue>> for RuntimeArgs

fn into(self) -> BTreeMap<String, CLValue>

Performs the conversion.

impl Ord for RuntimeArgs

fn cmp(&self, other: &RuntimeArgs) -> Ordering

This method returns an Ordering between self and other.

#[must_use]pub fn max(self, other: Self) -> Self

Compares and returns the maximum of two values.

#[must_use]pub fn min(self, other: Self) -> Self

Compares and returns the minimum of two values.

#[must_use]pub fn clamp(self, min: Self, max: Self) -> Self

Restrict a value to a certain interval.

impl PartialEq<RuntimeArgs> for RuntimeArgs

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

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=.

impl PartialOrd<RuntimeArgs> for RuntimeArgs

fn partial_cmp(&self, other: &RuntimeArgs) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

#[must_use]pub fn lt(&self, other: &Rhs) -> bool

This method tests less than (for self and other) and is used by the < operator.

#[must_use]pub fn le(&self, other: &Rhs) -> bool

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

#[must_use]pub fn gt(&self, other: &Rhs) -> bool

This method tests greater than (for self and other) and is used by the > operator.

#[must_use]pub fn ge(&self, other: &Rhs) -> bool

This method tests greater than or equal to (for self and other) and is used by the >= operator.

impl Serialize for RuntimeArgs

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

Serialize this value into the given Serde serializer.

impl StructuralEq for RuntimeArgs

impl StructuralPartialEq for RuntimeArgs

impl ToBytes for RuntimeArgs

fn to_bytes(&self) -> Result<Vec<u8>, Error>

Serializes &self to a Vec<u8>.

fn serialized_length(&self) -> usize

Returns the length of the Vec<u8> which would be returned from a successful call to to_bytes() or into_bytes(). The data is not actually serialized, so this call is relatively cheap.

fn into_bytes(self) -> Result<Vec<u8>, Error> where
    Self: Sized, 

Consumes self and serializes to a Vec<u8>.
