Struct PaymentStrParams 

pub struct PaymentStrParams<'a> { /* private fields */ }

Container for payment-related arguments used while constructing a Deploy.

payment_args_simple

For methods taking payment_args_simple, this parameter is the payment contract arguments, in the form <NAME:TYPE='VALUE'> or <NAME:TYPE=null>.

It can only be used with the following simple CLTypes: bool, i32, i64, u8, u32, u64, u128, u256, u512, unit, string, key, account_hash, uref, public_key and Option of each of these.

Example inputs are:

name_01:bool='false'
name_02:i32='-1'
name_03:i64='-2'
name_04:u8='3'
name_05:u32='4'
name_06:u64='5'
name_07:u128='6'
name_08:u256='7'
name_09:u512='8'
name_10:unit=''
name_11:string='a value'
key_account_name:key='account-hash-0102030405060708090a0b0c0d0e0f101112131415161718191a1b1c1d1e1f20'
key_hash_name:key='hash-0102030405060708090a0b0c0d0e0f101112131415161718191a1b1c1d1e1f20'
key_uref_name:key='uref-0102030405060708090a0b0c0d0e0f101112131415161718191a1b1c1d1e1f20-000'
account_hash_name:account_hash='account-hash-0102030405060708090a0b0c0d0e0f101112131415161718191a1b1c1d1e1f20'
uref_name:uref='uref-0102030405060708090a0b0c0d0e0f101112131415161718191a1b1c1d1e1f20-007'
public_key_name:public_key='0119bf44096984cdfe8541bac167dc3b96c85086aa30b6b6cb0c5c38ad703166e1'

For optional values of any these types, prefix the type with “opt_” and use the term “null” without quotes to specify a None value:

name_01:opt_bool='true'       # Some(true)
name_02:opt_bool='false'      # Some(false)
name_03:opt_bool=null         # None
name_04:opt_i32='-1'          # Some(-1)
name_05:opt_i32=null          # None
name_06:opt_unit=''           # Some(())
name_07:opt_unit=null         # None
name_08:opt_string='a value'  # Some("a value".to_string())
name_09:opt_string='null'     # Some("null".to_string())
name_10:opt_string=null       # None

To get a list of supported types, call cli::simple_args_help::supported_cl_type_list. To get this list of examples for supported types, call cli::simple_args_help::supported_cl_type_examples.

payment_args_json

For methods taking payment_args_json, this parameter is the payment contract arguments, as a JSON-encoded Array of JSON Objects of the form:

[{"name":<String>,"type":<VALUE>,"value":<VALUE>}]

To get comprehensive information and a set of examples, call cli::json_args_help::info_and_examples.

Example inputs are:

[{"name":"a","type":"Bool","value":false}]
[{"name":"b","type":"I32","value":-1}]
[{"name":"c","type":"U64","value":1}]
[{"name":"d","type":"U512","value":"20000000000000000000"}]
[{"name":"e","type":"Unit","value":null}]
[{"name":"f","type":"String","value":"a"}]
[{"name":"g","type":"Key","value":"account-hash-201f1e1d1c1b1a191817161514131211100f0e0d0c0b0a090807060504030201"}]
[{"name":"h","type":"URef","value":"uref-201f1e1d1c1b1a191817161514131211100f0e0d0c0b0a090807060504030201-007"}]
[{"name":"i","type":"PublicKey","value":"017279ea868d185a40ed32ec076807c070de9c0fe986f5418c2aa71478f1e8ddf8"}]
[{"name":"j","type":{"Option":"U64"},"value":999}]        # Some(999_u64)
[{"name":"k","type":{"Option":"String"},"value":null}]    # None
[{"name":"l","type":{"List":{"Option":"U256"}},"value":[1,null,"3"]}]
[{"name":"m","type":{"List":"U8"},"value":"0102ff"}]      # for Vec<u8> only, can parse from hex string
[{"name":"n","type":{"ByteArray":3},"value":"0114ff"}]
[{"name":"o","type":{"ByteArray":3},"value":[1,20,255]}]
[{"name":"p","type":{"Result":{"ok":"Bool","err":"U8"}},"value":{"Ok":true}}]
[{"name":"q","type":{"Result":{"ok":"Bool","err":"U8"}},"value":{"Err":1}}]
[{"name":"r","type":{"Map":{"key":"U8","value":"Bool"}},"value":[{"key":1,"value":true},{"key":2,"value":false}]}]
## for Map with key as String or Number can use an Object rather than an Array:
[{"name":"s","type":{"Map":{"key":"U8","value":"Bool"}},"value":{"1":true,"2":false}}]
[{"name":"t","type":{"Tuple3":["Bool","U8","String"]},"value":[true,128,"a"]}]

---

Note while multiple payment args can be specified for a single payment code instance, only one of payment_args_simple, or payment_args_json may be used.

Implementations

impl<'a> PaymentStrParams<'a>

pub fn with_path( payment_path: &'a str, payment_args_simple: Vec<&'a str>, payment_args_json: &'a str, ) -> Self

Constructs a PaymentStrParams using a payment smart contract file.

• payment_path is the path to the compiled Wasm payment code.
• See the struct docs for a description of payment_args_simple, payment_args_json

pub fn with_amount(payment_amount: &'a str) -> Self

Constructs a PaymentStrParams using a payment amount.

payment_amount uses the standard-payment system contract rather than custom payment Wasm. The value is the ‘amount’ arg of the standard-payment contract.

pub fn with_name( payment_name: &'a str, payment_entry_point: &'a str, payment_args_simple: Vec<&'a str>, payment_args_json: &'a str, ) -> Self

Constructs a PaymentStrParams using a stored contract’s name.

• payment_name is the name of the stored contract (associated with the executing account) to be called as the payment.
• payment_entry_point is the name of the method that will be used when calling the payment contract.
• See the struct docs for a description of payment_args_simple, payment_args_json

pub fn with_hash( payment_hash: &'a str, payment_entry_point: &'a str, payment_args_simple: Vec<&'a str>, payment_args_json: &'a str, ) -> Self

Constructs a PaymentStrParams using a stored contract’s hex-encoded hash.

• payment_hash is the hex-encoded hash of the stored contract to be called as the payment.
• payment_entry_point is the name of the method that will be used when calling the payment contract.
• See the struct docs for a description of payment_args_simple, payment_args_json

pub fn with_package_name( payment_package_name: &'a str, payment_version: &'a str, payment_entry_point: &'a str, payment_args_simple: Vec<&'a str>, payment_args_json: &'a str, ) -> Self

Constructs a PaymentStrParams using a stored contract’s package name.

• payment_package_name is the name of the stored package to be called as the payment.
• payment_version is the version of the called payment contract. The latest will be used if payment_version is empty.
• payment_entry_point is the name of the method that will be used when calling the payment contract.
• See the struct docs for a description of payment_args_simple, payment_args_json

pub fn with_package_hash( payment_package_hash: &'a str, payment_version: &'a str, payment_entry_point: &'a str, payment_args_simple: Vec<&'a str>, payment_args_json: &'a str, ) -> Self

Constructs a PaymentStrParams using a stored contract’s package hash.

• payment_package_hash is the hex-encoded hash of the stored package to be called as the payment.
• payment_version is the version of the called payment contract. The latest will be used if payment_version is empty.
• payment_entry_point is the name of the method that will be used when calling the payment contract.
• See the struct docs for a description of payment_args_simple, payment_args_json

Trait Implementations

impl<'a> Debug for PaymentStrParams<'a>
