Enum ErrorKind 

#[non_exhaustive]
pub enum ErrorKind {
    TooManyVMPages,
    UnknownPageSize,
    InvalidPageSize(u64),
    #[non_exhaustive]
    Io {
        operation: &'static str,
        error: Arc<Error>,
        process_id: Option<pid_t>,
    },
    #[non_exhaustive]
    IntegerCast(TryFromIntError),
}

Actual storage for an error.

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.

TooManyVMPages

Virtual memory address range contains too many pages.

UnknownPageSize

Failed to query the system page size.

InvalidPageSize(u64)

Invalid system page size.

#[non_exhaustive]

Io

Some io::Error occurred.

Fields

Non-exhaustive enum variants could have additional fields added in future. Therefore, non-exhaustive enum variants cannot be constructed in external crates and cannot be matched against.

operation: &'static str

Name of the I/O operation that generated the error.

error: Arc<Error>

The io::Error that occurred.

process_id: Option<pid_t>

Identifier of the process that was the target of the I/O.

#[non_exhaustive]

IntegerCast(TryFromIntError)

Casting an integer caused data loss.
