Member Function Documentation

◆ Arg()

template<typename R >

auto RPCHelpMan::Arg ( std::string_view key ) const

inline

Helper to get a required or default-valued request argument.

Use this function when the argument is required or when it has a default value. If the argument is optional and may not be provided, use MaybeArg instead.

This function only works during m_fun(), i.e., it should only be used in RPC method implementations. It internally checks whether the user-passed argument isNull() and parses (from JSON) and returns the user-passed argument, or the default value derived from the RPCArg documentation.

The instantiation of this helper for type R must match the corresponding RPCArg::Type.

Returns: The value of the RPC argument (or the default value) cast to type R.

See also: MaybeArg for handling optional arguments without default values.

◆ GetParamIndex()

bool RPCHelpMan::IsValidNumArgs ( size_t num_args ) const

If the supplied number of args is neither too small nor too high.

Definition at line 755 of file util.cpp.

Here is the caller graph for this function:

◆ MaybeArg()

template<typename R >

auto RPCHelpMan::MaybeArg ( std::string_view key ) const

inline

Helper to get an optional request argument.

Use this function when the argument is optional and does not have a default value. If the argument is required or has a default value, use Arg instead.

This function only works during m_fun(), i.e., it should only be used in RPC method implementations. It internally checks whether the user-passed argument isNull() and parses (from JSON) and returns the user-passed argument, or a falsy value if no argument was passed.

The instantiation of this helper for type R must match the corresponding RPCArg::Type.

Returns: For integral and floating-point types, a std::optional<R> is returned. For other types, a R* pointer to the argument is returned. If the argument is not provided, std::nullopt or a null pointer is returned.

See also: Arg for handling arguments that are required or have a default value.
