KernelWriter

Struct KernelWriter 

Source
pub struct KernelWriter {
    lock: IrqMutexGuard<'static, KernelPrintState>,
}
Expand description

RAII handle that holds the KPRINT_STATE lock for one kprint! call, preventing interleaved output.

Fields§

§lock: IrqMutexGuard<'static, KernelPrintState>

Implementations§

Source§

impl KernelWriter

Source

pub fn lock() -> Self

Acquire KPRINT_STATE and return a KernelWriter holding the guard.

Source

pub fn print_raw(&mut self, string: &str, color: Option<u32>)

Write string with an optional color to all active output sinks.
