[−][src]Enum nix::Error
Nix Error Type
The nix error type provides a common way of dealing with various system system/libc calls that might fail. Each error has a corresponding errno (usually the one from the underlying OS) to which it can be mapped in addition to implementing other common traits.
Variants
Sys(Errno)
The operation involved a conversion to Rust's native String type, which failed because the string did not contain all valid UTF-8.
The operation is not supported by Nix, in this instance either use the libc bindings or consult the module documentation to see if there is a more appropriate interface available.
Implementations
impl Error
[src]
pub fn as_errno(&self) -> Option<Errno>
[src]
Convert this Error
to an Errno
.
Example
let e = Error::from(Errno::EPERM); assert_eq!(Some(Errno::EPERM), e.as_errno());
pub fn from_errno(errno: Errno) -> Error
[src]
Create a nix Error from a given errno
pub fn last() -> Error
[src]
Get the current errno and convert it to a nix Error
pub fn invalid_argument() -> Error
[src]
Create a new invalid argument error (EINVAL
)
