Struct casper_types::CLValue[−][src]

pub struct CLValue { /* fields omitted */ }

Expand description

A Casper value, i.e. a value which can be stored and manipulated by smart contracts.

It holds the underlying data as a type-erased, serialized Vec<u8> and also holds the CLType of the underlying data as a separate member.

Implementations

[src]

impl CLValue

[src]

pub fn from_t<T: CLTyped + ToBytes>(t: T) -> Result<CLValue, CLValueError>

Constructs a CLValue from t.

[src]

pub fn into_t<T: CLTyped + FromBytes>(self) -> Result<T, CLValueError>

Consumes and converts self back into its underlying type.

[src]

pub fn unit() -> Self

A convenience method to create CLValue for a unit.

[src]

pub fn cl_type(&self) -> &CLType

The CLType of the underlying data.

[src]

pub fn inner_bytes(&self) -> &Vec<u8>

Returns a reference to the serialized form of the underlying value held in this CLValue.

[src]

pub fn serialized_length(&self) -> usize

Returns the length of the Vec<u8> yielded after calling self.to_bytes().

Note, this method doesn’t actually serialize self, and hence is relatively cheap.
