impl XcbPresent

pub unsafe fn load() -> Result<Self, Error>

Loads the library from the default location.

pub unsafe fn load_loose() -> Result<Self, Error>

Loads the library from the default location, potentially loading an incompatible SO version.

For example, this function first tries to load libxcb.so.1. If this fails, it tries to load libxcb.so.

pub unsafe fn load_from(path: impl AsRef<Path>) -> Result<Self, Error>

Loads the library from the specified path.
