Struct Argument

pub struct Argument<T> { /* private fields */ }

This is our argument builder.

Implementations

impl Argument<Vec<Value>>

Argument builder assuming a vec

pub fn array(values: Vec<Value>) -> Argument<Vec<Value>>

Argument from array

pub fn dictionary(values: Vec<(String, String)>) -> Argument<Vec<Value>>

Argument from dictionary Vec<(String, String)>

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

impl Argument<bool>

Boolean arguments

pub fn boolean(value: bool) -> Argument<bool>

impl Argument<&str>

You can use this to avoid memory allocation when dealing only with str

pub fn str(value: &str) -> Argument<&str>

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

impl Argument<String>

You will use this for most argument types. Before implementing new types, be sure to read https://docs.onflow.org/cadence/json-cadence-spec

pub fn string(value: String) -> Argument<String>

Take a String and turn it into an argument

pub fn ufix64(value: f64) -> Argument<String>

Take a positive f64 and turn it into an argument. Fixed point numbers are encoded as strings, so this will result in additional memory allocation when used.

pub fn fix64(value: f64) -> Argument<String>

Take a f64 and turn it into an argument. Fixed point numbers are encoded as strings, so this will result in additional memory allocation when used.

pub fn uint64(value: u64) -> Argument<String>

Take a u64 and turn it into an argument. Integers are encoded as strings, so this will result in additional memory allocation when used.

pub fn int64(value: i64) -> Argument<String>

Take a i64 and turn it into an argument. Integers are encoded as strings, so this will result in additional memory allocation when used.

pub fn address(value: String) -> Argument<String>

Take a hex-encoded string and turn it into an argument.

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

Trait Implementations

impl<T> Serialize for Argument<T>

where T: Serialize,

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
