Enum PosixSlotError 

#[non_exhaustive]
pub enum PosixSlotError {
    Shm(ShmemError),
    CapacityOverflow,
    InvalidHeader,
    Slot(SlotError),
}

Error while setting up the POSIX segment.

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.

Shm(ShmemError)

Shm backend error.

CapacityOverflow

Slot capacity too large for u32.

InvalidHeader

Segment header does not match (different owner / wrong magic).

Slot(SlotError)

Internal slot error (passes through).

Trait Implementations

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
