Function macro_tools::protected::typ::is_optional

pub fn is_optional(ty: &Type) -> bool

Checks if a given syn::Type is an Option type.

This function examines a type to determine if it represents an Option. It is useful for scenarios where type-specific behavior needs to be conditional on whether the type is optional or not.

Example

let type_string = "Option< i32 >";
let parsed_type : syn::Type = syn::parse_str( type_string ).expect( "Type should parse correctly" );
assert!( macro_tools::typ::is_optional( &parsed_type ) );
