Enum FwCfgWriteError 

#[non_exhaustive]
pub enum FwCfgWriteError {
    DmaNotAvailable,
    DmaFailed,
}

An enum type for [FwCfg::write_file] errors.

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.

DmaNotAvailable

This fw_cfg device does not support DMA access, which is necessary for writing since QEMU v2.4.

Note: writing through the data register for older QEMU versions is not supported by this crate.

DmaFailed

Something went wrong during a DMA write

Trait Implementations

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

Formats the value using the given formatter.

impl PartialEq for FwCfgWriteError

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
