Struct sgx_tstd::io::Error [−][src]
pub struct Error { /* fields omitted */ }
The error type for I/O operations of the Read
, Write
, Seek
, and
associated traits.
Errors mostly originate from the underlying OS, but custom instances of
Error
can be created with crafted error messages and a particular value of
ErrorKind
.
Methods
impl Error
[src]
impl Error
pub fn new<E>(kind: ErrorKind, error: E) -> Error where
E: Into<Box<Error + Send + Sync>>,
[src]
pub fn new<E>(kind: ErrorKind, error: E) -> Error where
E: Into<Box<Error + Send + Sync>>,
Creates a new I/O error from a known kind of error as well as an arbitrary error payload.
This function is used to generically create I/O errors which do not
originate from the OS itself. The error
argument is an arbitrary
payload which will be contained in this Error
.
pub fn last_os_error() -> Error
[src]
pub fn last_os_error() -> Error
Returns an error representing the last OS error which occurred.
This function reads the value of errno
for the target platform (e.g.
GetLastError
on Windows) and will return a corresponding instance of
Error
for the error code.
pub fn from_raw_os_error(code: i32) -> Error
[src]
pub fn from_raw_os_error(code: i32) -> Error
Creates a new instance of an Error
from a particular OS error code.
pub fn raw_os_error(&self) -> Option<i32>
[src]
pub fn raw_os_error(&self) -> Option<i32>
Returns the OS error that this error represents (if any).
If this Error
was constructed via last_os_error
or
from_raw_os_error
, then this function will return Some
, otherwise
it will return None
.
pub fn from_sgx_error(status: sgx_status_t) -> Error
[src]
pub fn from_sgx_error(status: sgx_status_t) -> Error
Creates a new instance of an Error
from a particular SGX error status.
pub fn raw_sgx_error(&self) -> Option<sgx_status_t>
[src]
pub fn raw_sgx_error(&self) -> Option<sgx_status_t>
Returns the SGX error that this error represents (if any).
If this Error
was constructed via from_sgx_error
or
then this function will return Some
, otherwise
it will return None
.
pub fn get_ref(&self) -> Option<&(Error + Send + Sync + 'static)>
[src]
pub fn get_ref(&self) -> Option<&(Error + Send + Sync + 'static)>
Returns a reference to the inner error wrapped by this error (if any).
If this Error
was constructed via new
then this function will
return Some
, otherwise it will return None
.
pub fn get_mut(&mut self) -> Option<&mut (Error + Send + Sync + 'static)>
[src]
pub fn get_mut(&mut self) -> Option<&mut (Error + Send + Sync + 'static)>
Returns a mutable reference to the inner error wrapped by this error (if any).
If this Error
was constructed via new
then this function will
return Some
, otherwise it will return None
.
pub fn into_inner(self) -> Option<Box<Error + Send + Sync>>
[src]
pub fn into_inner(self) -> Option<Box<Error + Send + Sync>>
Consumes the Error
, returning its inner error (if any).
If this Error
was constructed via new
then this function will
return Some
, otherwise it will return None
.
pub fn kind(&self) -> ErrorKind
[src]
pub fn kind(&self) -> ErrorKind
Returns the corresponding ErrorKind
for this error.
