Struct firmware_uefi::service::nvram::spec_services::NvramResult

source · 
pub struct NvramResult<T>(pub T, pub EfiStatus, pub Option<NvramError>);
Expand description

Unlike a typical result type, NvramErrors contain both a payload and an error code. Depending on the error code, an optional NvramError might be included as well, which provides more context.

Notably, this result types cannot be propagated via the ? operator!
