Enum ScreenError 

pub enum ScreenError {
    ConcurrentAccess,
    CopyBufferWrongSize {
        buffer_size: usize,
        expected_size: usize,
    },
}

Errors that can occur when interacting with the screen.

Variants

ConcurrentAccess

Another resource is currently trying to access the screen mutex.

CopyBufferWrongSize

The given buffer of colors was wrong size to fill the specified area.

Fields

buffer_size: usize

The size of the buffer.

expected_size: usize

The expected size of the buffer.

Trait Implementations

impl Debug for ScreenError

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

Formats the value using the given formatter.

impl Display for ScreenError

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

Formats the value using the given formatter.

impl Error for ScreenError

where Self: Debug + Display,

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

Returns the lower-level source of this error, if any.

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.

impl ErrorCompat for ScreenError

fn backtrace(&self) -> Option<&Backtrace>

Returns a Backtrace that may be printed.

fn iter_chain(&self) -> ChainCompat<'_, '_>

where Self: AsErrorSource,

Returns an iterator for traversing the chain of errors, starting with the current error and continuing with recursive calls to Error::source.

impl FromErrno for ScreenError

fn from_errno(num: i32) -> Option<Self>

Consume the current errno and, if it contains a known error, returns Self.
