Enum winproc::errors::Error

pub enum Error {
    Os(Error),
    NoProcess(String),
    NulError(NulError),
    NulErrorW {
        pos: usize,
        data: Vec<u16>,
    },
}

A Windows process error.

Variants

Os(Error)

A Windows error.

NoProcess(String)

No process found during a search.

NulError(NulError)

An invalid nul value was found in a UTF-8 string.

NulErrorW

An invalid nul value was found in a UTF-16 string vector.

The error indicates the position in the vector where the nul value was found, as well as returning the ownership of the invalid vector.

Fields of NulErrorW

pos: usize
data: Vec<u16>

Methods

impl Error

pub fn code(&self) -> Option<u32>

pub fn last_os_error() -> Error

Returns the last windows error.

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Fail for Error

fn cause(&self) -> Option<&Fail>

Returns a reference to the underlying cause of this failure, if it is an error that wraps other errors.

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

Returns a reference to the Backtrace carried by this failure, if it carries one.

fn context<D>(self, context: D) -> Context<D> where     D: Display + Send + Sync + 'static,

Provides context for this failure.

fn compat(self) -> Compat<Self>

Wraps this failure in a compatibility wrapper that implements std::error::Error.

Important traits for Causes<'f>

impl<'f> Iterator for Causes<'f> type Item = &'f (Fail + 'static);

fn causes(&self) -> Causes

Returns a iterator over the causes of this Fail with itself as the first item and the root_cause as the final item.

fn root_cause(&self) -> &(Fail + 'static)

Returns the "root cause" of this Fail - the last value in the cause chain which does not return an underlying cause.

impl Display for Error

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

Formats the value using the given formatter.

impl From<NulError> for Error

fn from(e: NulError) -> Error

Performs the conversion.
