 The `render` function provides an **extremely efficient** allocator for VNodes and text, so try not to use the `format!` macro in your components. Rust's default `ToString` methods pass through the global allocator, but all text in components is allocated inside a manually-managed Bump arena. To push you in the right direction, all text-based attributes take `std::fmt::Arguments` directly, so you'll want to reach for `format_args!` when the built-in `f-string` interpolation just doesn't cut it.

 A função `render` fornece um alocador **extremamente eficiente** para `VNodes` e `text`, então tente não usar a macro `format!` em seus componentes. Os métodos `ToString` padrão do Rust passam pelo alocador global, mas todo o texto nos componentes é alocado dentro de uma ""arena Bump"" gerenciada manualmente. Para levá-lo na direção certa, todos os atributos baseados em texto recebem `std::fmt::Arguments` diretamente, então você vai querer usar `format_args!` quando a interpolação interna `f-string` simplesmente não funcionar.
