Implementations

impl ResolvedArgs

pub fn get<T>(&self, name: Name) -> Result<T, CallError>

where T: TryFrom<Value>, <T as TryFrom<Value>>::Error: ToString,

Get a named argument.

The argument is converted to the expected type with TryFrom.

pub fn get_opt<T>(&self, name: Name) -> Result<Option<T>, CallError>

where T: TryFrom<Value>, <T as TryFrom<Value>>::Error: ToString,

Get an optional named argument.

pub fn get_map<T, F, E>(&self, name: Name, check: F) -> Result<T, CallError>

where F: Fn(Value) -> Result<T, E>, E: ToString,

Get a named argument.

The check function is responsible for checking that the argument is valid and converting it to the correct type.

pub fn get_opt_map<T, F>( &self, name: Name, check: F ) -> Result<Option<T>, CallError>

where F: Fn(Value) -> Result<T, String>,

Get an optional named argument.

pub fn call_scope(&self) -> ScopeRef

Get the scope from this the function was called.
