Enum CpuRetentionMemoryError 

#[non_exhaustive]
pub enum CpuRetentionMemoryError {
    OutOfRange,
    AlreadyInstalled,
}

Available on crate feature unstable only.

The reason why LowPower::install_cpu_retention_memory refused a buffer.

Stability

This API is marked as unstable and is only available when the unstable crate feature is enabled. This comes with no stability guarantees, and could be changed or removed at any time.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

OutOfRange

The buffer is not inside the range that retention needs.

AlreadyInstalled

The driver holds a retention buffer already.
