Struct CallArgs 

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

Represents a collection of arguments passed to a smart contract entrypoint call.

Wraps casper’s RuntimeArgs.

Implementations

impl CallArgs

pub fn new() -> Self

Creates a new no-args instance.

pub fn insert<K, V>(&mut self, key: K, value: V)

where K: Into<String>, V: CLTyped + ToBytes,

Inserts a new empty arg into the collection.

pub fn arg_names(&self) -> Vec<String>

Retrieves a vector of argument names.

pub fn as_casper_runtime_args(&self) -> &RuntimeArgs

Return Casper’s RuntimeArgs.

Methods from Deref<Target = RuntimeArgs>

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

Gets an argument by its name.

pub fn len(&self) -> usize

Gets the length of the collection.

pub fn is_empty(&self) -> bool

Returns true if the 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,

Inserts a new named argument into the collection.

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

where K: Into<String>,

Inserts a new named argument into the collection.

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

Returns all the values of the named args.

pub fn named_args(&self) -> impl Iterator<Item = &NamedArg>

Returns an iterator of references over all arguments in insertion order.

pub fn named_args_mut(&mut self) -> impl Iterator<Item = &mut NamedArg>

Returns an iterator of mutable references over all arguments in insertion order.

pub fn try_get_number(&self, name: &str) -> Result<U512, CLValueError>

Returns the numeric value of name arg from the runtime arguments or defaults to 0 if that arg doesn’t exist or is not an integer type.

Supported CLTypes for numeric conversions are U64, and U512.

Returns an error if parsing the arg fails.

Trait Implementations

impl CLTyped for CallArgs

fn cl_type() -> CLType

The CLType of Self.

impl Clone for CallArgs

fn clone(&self) -> CallArgs

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CallArgs

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

Formats the value using the given formatter.

impl Default for CallArgs

fn default() -> CallArgs

Returns the “default value” for a type.

impl Deref for CallArgs

type Target = RuntimeArgs

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.

impl DerefMut for CallArgs

fn deref_mut(&mut self) -> &mut Self::Target

Mutably dereferences the value.

impl FromBytes for CallArgs

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 ToBytes for CallArgs

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>.

fn write_bytes(&self, writer: &mut Vec<u8>) -> Result<(), Error>

Writes &self into a mutable writer.
