Enum ProtectionError 

#[non_exhaustive]
pub enum ProtectionError {
    Unsupported(&'static str),
    SyscallFailed {
        op: &'static str,
        code: i32,
    },
    DebuggerAttached(&'static str),
}

Process protection application failure.

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.

Unsupported(&'static str)

Platform or primitive unsupported — macOS mlockall absence is representative.

SyscallFailed

Syscall failure (errno + platform-specific detail go through the log path).

Fields

op: &'static str

syscall / API name.

code: i32

Platform errno or HRESULT.

DebuggerAttached(&'static str)

Protection applied while a debugger / ptracer is already attached. If disable_ptrace() only emits a silent warn, a caller could misread .is_ok() as “no debugger”. This variant is the explicit signal — operator should detach and retry, or fail-close at startup (Tier-0 policy).

Trait Implementations

impl Debug for ProtectionError

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

Formats the value using the given formatter.

impl Display for ProtectionError

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

Formats the value using the given formatter.

impl Error for ProtectionError

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

Returns the lower-level source of this error, if any.

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

fn provide<'a>(&'a self, request: &mut Request<'a>)

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

Provides type-based access to context intended for error reports.
