Struct MemoryLockError 

pub struct MemoryLockError {
    pub operation: MemoryLockOperation,
    pub errno: i32,
}

Error returned by platform memory-locking operations.

If setup and the subsequent cleanup unmap both fail, the returned error reports Unmap. A mapping that may still be live takes diagnostic precedence over the original setup failure.

Fields

operation: MemoryLockOperation

Operation that failed.

errno: i32

Positive errno or Windows GetLastError value when available.

This is 0 for local arithmetic failures before a syscall. Negative values are crate-internal sentinel failures, such as an unsupported random-canary backend or a random backend that made no progress.
