Enum FbInfoError 

#[non_exhaustive]
pub enum FbInfoError {
    Unparsable {
        attribute: &'static str,
    },
    UnsupportedDepth {
        bits_per_pixel: u32,
    },
    EmptyGeometry,
    StrideTooNarrow {
        stride_bytes: u32,
        required: u32,
    },
}

Why a framebuffer’s geometry could not be understood.

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.

Unparsable

A sysfs attribute did not hold what it should.

Fields

attribute: &'static str

Which attribute.

UnsupportedDepth

The depth is not one this backend can drive.

Fields

bits_per_pixel: u32

The depth reported.

EmptyGeometry

The framebuffer reported a zero dimension.

StrideTooNarrow

The reported stride cannot hold one row.

Fields

stride_bytes: u32

The stride reported.

required: u32

What one row needs.

impl Eq for FbInfoError

impl Error for FbInfoError

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 From<FbInfoError> for FbdevError

fn from(source: FbInfoError) -> Self

Converts to this type from the input type.

impl PartialEq for FbInfoError

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

Equality operator ==.

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

Inequality operator !=.
