Enum Params

pub enum Params {
    Positional(Vec<Value>),
    Named(Map<String, Value>),
}

Represetaion of jsonrpc arguments. Passing no arguments is assumed to be semantically equivalent to passing 0 positional args, or passing a map with zero entries.

Users of this library will rarely need to deal with this type.

Variants

Positional(Vec<Value>)

Arguments were either not present (expressed as a length 0 list), or arguments were provided as a json list.

Named(Map<String, Value>)

Arguments were provided as a json dictionary.

Implementations

impl Params

pub fn get_rpc_args( self, names: &[&'static str], ) -> Result<Vec<Value>, InvalidArgs>

Verify and convert Params to an argument list. If arguments are provided as named parameters, interpret them as positional arguments using the names argument as a key.

Verifies:

• Number of args in positional parameter list is correct
• No missing args in named parameter object
• No extra args in named parameter object

Trait Implementations

impl Debug for Params

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

Formats the value using the given formatter.
