Enum SamplingError 

pub enum SamplingError {
    Io(Error),
    InvalidData(&'static str),
    CommandFailed {
        program: PathBuf,
        status: ExitStatus,
    },
    UnsupportedHost,
}

Failure to observe a native process table or sum its resident bytes.

Variants

Io(Error)

Native filesystem or process invocation failed.

InvalidData(&'static str)

A native record was malformed or its byte arithmetic overflowed.

CommandFailed

The native process-table command failed.

Fields

program: PathBuf

Executed native program.

status: ExitStatus

Original exit status.

UnsupportedHost

This host has no supported process-table observation backend.

Trait Implementations

impl Debug for SamplingError

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

Formats the value using the given formatter.

impl Display for SamplingError

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

Formats the value using the given formatter.

impl Error for SamplingError

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.

impl From<Error> for SamplingError

fn from(error: Error) -> Self

Converts to this type from the input type.
