Methods
impl PCM[src]
pub fn new(name: &str, dir: Direction, nonblock: bool) -> Result<PCM>[src]
Wrapper around open that takes a &str instead of a &CStr
pub fn open(name: &CStr, dir: Direction, nonblock: bool) -> Result<PCM>[src]

pub fn recover(&self, err: c_int, silent: bool) -> Result<()>[src]
pub fn try_recover(&self, err: Error, silent: bool) -> Result<()>[src]
Wrapper around snd_pcm_recover.
Returns Ok if the error was successfully recovered from, or the original error if the error was unhandled.

ⓘImportant traits for IO<'a, S>
pub fn direct_mmap_capture<S>(&self) -> Result<MmapCapture<S>>[src]
Read buffers by talking to the kernel directly, bypassing alsa-lib.

Write buffers by talking to the kernel directly, bypassing alsa-lib.
pub fn hw_params(&self, h: &HwParams) -> Result<()>[src]
Sets hw parameters. Note: No IO object can exist for this PCM when hw parameters are set.
pub fn hw_params_current<'a>(&'a self) -> Result<HwParams<'a>>[src]
Retreive current PCM hardware configuration.
