Enum DmaBufError 

#[non_exhaustive]
pub enum DmaBufError {
    NoBuffers,
    NoPlanes,
    InvalidBufferIndex {
        plane: usize,
        buffer_index: u32,
    },
    ZeroStride {
        plane: usize,
    },
}

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.

impl Eq for DmaBufError

impl Error for DmaBufError

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 DmaBufError

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

Equality operator ==.

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