Trait RenderBackend 

Source 
pub trait RenderBackend: Any {
    // Required methods
    fn as_any_mut(&mut self) -> &mut dyn Any;
    fn acquire_mask(&mut self) -> &mut [u8] ⓘ;
}
Expand description

Opaque render backend trait with downcasting capability. Core crate defines this trait; UI crates downcast to concrete implementations. This enables true backend independence — core compiles without Ratatui.

Required Methods§

Source

fn as_any_mut(&mut self) -> &mut dyn Any

Downcast to concrete backend type.

Source

fn acquire_mask(&mut self) -> &mut [u8] ⓘ

Returns a zero-initialized persistent mask slice sized to the current buffer. The mask is a flat Vec<u8> that decouples conditional string checks from bitwise buffer mutation — enabling SIMD-friendly two-pass rendering. Allocates only when the buffer grows; zero allocations in steady state.

Dyn Compatibility§

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
