Struct concordium_std::ContractName

pub struct ContractName<'a>(_);

A contract name. Expected format: “init_<contract_name>”.

Implementations

impl<'a> ContractName<'a>

pub fn new(name: &'a str) -> Result<ContractName<'a>, NewContractNameError>

Create a new ContractName and check the format. Expected format: “init_<contract_name>”.

pub fn new_unchecked(name: &'a str) -> ContractName<'a>

Create a new ContractName without checking the format. Expected format: “init_<contract_name>”. If this precondition is not satisfied then the behaviour of any methods on this type is unspecified, and may include panics.

pub fn get_chain_name(self) -> &'a str

Get contract name used on chain: “init_<contract_name>”.

pub fn contract_name(self) -> &'a str

Extract the contract name by removing the “init_” prefix.

pub fn is_valid_contract_name(name: &str) -> Result<(), NewContractNameError>

Check whether the given string is a valid contract initialization function name. This is the case if and only if

• the string is no more than constants::MAX_FUNC_NAME_SIZE bytes
• the string starts with init_
• the string does not contain a .
• all characters are ascii alphanumeric or punctuation characters.
