Enum ReserveError 

#[non_exhaustive]
pub enum ReserveError {
    Shortfall {
        crtc_index: u32,
        wanted: usize,
        found: usize,
    },
}

Why a reservation could not be made.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Shortfall

Not enough planes on this CRTC match what was asked for.

Distinct from a hard failure: a caller can ask again for fewer, or draw its decorations into the window instead. It is a shortfall, not a broken device.

Fields

crtc_index: u32

Which CRTC.

wanted: usize

How many were asked for.

found: usize

How many matched.

Trait Implementations

impl Clone for ReserveError

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ReserveError

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

Formats the value using the given formatter.

Formats the value using the given formatter.

impl Eq for ReserveError

impl Error for ReserveError

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.

impl PartialEq for ReserveError

fn eq(&self, other: &Self) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
