Enum AcquireError 

pub enum AcquireError {
    WouldBlock,
    Invalidated,
}

Why acquire returned no slot.

Variants

WouldBlock

Every slot is being written, or still referenced by retained scenes or in-flight composition. Retry after the next presented frame.

Invalidated

The surface was invalidated (its engine device was lost). Create a new surface on a new engine device; the last frame keeps displaying.

impl Eq for AcquireError

impl Error for AcquireError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting
