Struct tartan_arch::aarch64::interrupt::Class

source ·
pub struct Class(/* private fields */);
Available on AArch64 only.
Expand description

Classifies different exception causes.

Note that the Arm documentation defines more variants than are defined in this type. This only includes exception classes that can be triggered from Aarch64 state and taken to EL1.

source

pub const fn name(self) -> Option<&'static str>

The name of the enum variant in code, if one is defined for this value.

An identical method is available through the CEnum trait, but this version is declared const (which is currently unstable on traits).
