Enum IoError 

pub enum IoError {
    BufferTooBig(usize),
    UnsupportedStrides,
    InvalidHandle,
    Unknown(String),
}

Error returned from create/read/write functions. Due to async execution not all errors are able to be caught, so some IO errors will still panic.

Variants

BufferTooBig(usize)

Buffer size exceeds the max available

UnsupportedStrides

Strides aren’t supported for this copy operation on this runtime

InvalidHandle

Handle wasn’t found in the memory pool

Unknown(String)

Unknown error happened during execution

Trait Implementations

impl Debug for IoError

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

Formats the value using the given formatter.

impl Display for IoError

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

Formats the value using the given formatter.

impl Error for IoError

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.
