Struct PerformanceCounter 

pub struct PerformanceCounter { /* private fields */ }

Performance counter for measuring rendering performance

Timing Requirements: This module requires the perfcounter feature and a timing source:

• For embedded with Embassy: enable both perfcounter and embassy-time features
• For desktop/simulator: enable std feature (includes perfcounter automatically)
• Without a timing source, timing will always return 0

Example

# For embedded with Embassy:
embedded-3dgfx = { version = "0.1", features = ["perfcounter", "embassy-time"] }

# For desktop/simulator:
embedded-3dgfx = { version = "0.1", features = ["std"] }

# Pure no_std without perfcounter:
embedded-3dgfx = { version = "0.1", default-features = false }
