Enum region::Error

pub enum Error {
    UnmappedRegion,
    InvalidParameter(&'static str),
    ProcfsInput(String),
    SystemCall(Error),
    MachCall(c_int),
}

A collection of possible errors.

Variants

UnmappedRegion

The queried memory is unmapped.

This does not necessarily mean that the memory region is available for allocation. Besides OS-specific semantics, queried addresses outside of a process’ adress range are also identified as unmapped regions.

InvalidParameter(&'static str)

A supplied parameter is invalid.

ProcfsInput(String)

A procfs region could not be parsed.

SystemCall(Error)

A system call failed.

MachCall(c_int)

A macOS kernel call failed

Trait Implementations

impl Debug for Error

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for Error

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Error for Error

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

The lower-level source of this error, if any.

fn backtrace(&self) -> Option<&Backtrace>

🔬 This is a nightly-only experimental API. (backtrace)

Returns a stack backtrace, if available, of where this error occurred.

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
