Struct error_code::ErrorCode[−][src]

pub struct ErrorCode<C> { /* fields omitted */ }
Expand description

Describes error code in particular category.

Implementations

impl ErrorCode<PosixCategory>[src]

pub fn last() -> Self[src]

Retrieves last error, generated by runtime

pub const fn unimplemented() -> Self[src]

Creates unimplemented error

pub const fn is_would_block(self) -> bool[src]

Returns whether underlying error means to try again.

Under POSIX, it means either EWOULDBLOCK or EAGAIN, in some cases it can be the same error code.

impl ErrorCode<SystemCategory>[src]

pub fn last() -> Self[src]

Retrieves last error, generated by OS

pub const fn unimplemented() -> Self[src]

Creates unimplemented error

pub const fn is_would_block(self) -> bool[src]

Returns whether underlying error means to try again.

Under POSIX, it means either EWOULDBLOCK or EAGAIN, in some cases it can be the same error code. In case of Windows, it is also WSAEWOULDBLOCK

impl<C> ErrorCode<C>[src]

pub const fn new(code: i32) -> Self[src]

Creates new error code in provided category.

pub const fn raw_code(self) -> i32[src]

Access raw integer code

pub const fn is_zero(self) -> bool[src]

Returns whether error code is zero.

Commonly zero is indication of no error.

impl<C: Category> ErrorCode<C>[src]

pub fn message(self) -> Str[src]

Returns textual representation of the error code

pub fn into_another<O: Category>(self) -> ErrorCode<O> where
    C: IntoCategory<O>, [src]

Converts self into error code of another category.

Requires self’s category to implement IntoCategory for destination category.
