Struct concordium_std::ContractName

pub struct ContractName<'a>(/* private fields */);

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

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

pub fn to_owned(&self) -> OwnedContractName

Convert a ContractName to its owned counterpart. This is an expensive operation that requires memory allocation.

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.

Trait Implementations

impl<'a> Clone for ContractName<'a>

fn clone(&self) -> ContractName<'a>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'a> Debug for ContractName<'a>

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

Formats the value using the given formatter.

impl<'a> Display for ContractName<'a>

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

Formats the value using the given formatter.

impl<'a> From<ContractName<'a>> for &'a str

fn from(n: ContractName<'a>) -> &'a str

Converts to this type from the input type.

impl<'a> Hash for ContractName<'a>

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

impl<'a> PartialEq<&'a str> for ContractName<'a>

fn eq(&self, other: &&'a str) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl<'a> PartialEq<str> for ContractName<'a>

fn eq(&self, other: &str) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl<'a> PartialEq for ContractName<'a>

fn eq(&self, other: &ContractName<'a>) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl<'a> Serial for ContractName<'a>

fn serial<W>(&self, out: &mut W) -> Result<(), <W as Write>::Err>

where W: Write,

Attempt to write the structure into the provided writer, failing if only part of the structure could be written.
