Error type for the RandomAccess trait methods.

Variants

OutOfBounds

Fields

offset: u64

Offset that was out of bounds

end: Option<u64>

If it was a range that was out of bounds, the end of the range.

length: u64

The length in the implementation that was exceeded.

Given parameters are out of bounds.

IO

Fields

return_code: Option<i32>

Optional system return code that caused the error.

context: Option<String>

Optional context of the error.

source: Error

Source of the error.

Unexpected std::io::Error.

Trait Implementations

impl Debug for RandomAccessError

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

Formats the value using the given formatter.

impl Display for RandomAccessError

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

Formats the value using the given formatter.

impl Error for RandomAccessError

fn source(&self) -> Option<&(dyn Error + 'static)>

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, demand: &mut Demand<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type based access to context intended for error reports.

impl From<Error> for RandomAccessError

fn from(err: Error) -> Self

Converts to this type from the input type.
