Struct SoftwareContext 

pub struct SoftwareContext { /* private fields */ }

Pure-CPU backend that stores everything in RAM. Useful for tests, CI, headless rendering, and platforms without any GPU API.

Implementations

impl SoftwareContext

pub fn new() -> Self

pub fn command_count(&self) -> usize

Number of recorded (but not yet cleared) commands.

pub fn drain_commands(&mut self) -> Vec<GpuCommand>

Drain the recorded commands for inspection.
