//! Parse components into the VComponent VNode
|

//! ==========================================
|
||||
//!
|
||||
//! This parsing path emerges from [`AmbiguousElement`] which supports validation of the vcomponent format.
|
||||
//! We can be reasonably sure that whatever enters this parsing path is in the right format.
|
||||
//! This feature must support
|
||||
//! - [x] Namespaced components
|
||||
//! - [x] Fields
|
||||
//! - [x] Componentbuilder synax
|
||||
//! - [x] Optional commas
|
||||
//! - [ ] Children
|
||||
//! - [ ] Keys
|
||||
//! - [ ] Properties spreading with with `..` syntax

//! Parse the root tokens in the rsx!{} macro
|
||||
//! =========================================
|
||||
//!
|
||||
//! This parsing path emerges directly from the macro call, with `RsxRender` being the primary entrance into parsing.
|
||||
//! This feature must support:
|
||||
//! - [x] Optionally rendering if the `in XYZ` pattern is present
|
||||
//! - [x] Fragments as top-level element (through ambiguous)
|
||||
//! - [x] Components as top-level element (through ambiguous)
|
||||
//! - [x] Tags as top-level elements (through ambiguous)
|
||||
//! - [x] Good errors if parsing fails
|
||||
//!
|
||||
//! Any errors in using rsx! will likely occur when people start using it, so the first errors must be really helpful.
