Struct linux_drm::event::UnsupportedDrmEvent

pub struct UnsupportedDrmEvent { /* private fields */ }

Raw owned representation of a DRM event of a type that this crate doesn’t directly support.

Implementations

impl UnsupportedDrmEvent

pub fn from_raw(raw: &DrmEvent) -> Self

pub fn typ(&self) -> u32

pub fn body_len(&self) -> usize

pub fn body_bytes(&self) -> &[u8]

Get the body of the event as a raw byte slice.

pub fn body_ptr<T: Sized>(&self) -> *const T

Get a pointer to the event body that interprets it as a value of T.

Dereferencing the returned pointer is undefined behavior unless the body is long enough to contain a T and contains a valid representation of T.

pub unsafe fn body_as<T>(&self) -> Option<&T>

Get a reference to the body interpreted as type T only if the body is at least long enough to fit a value of that type.

Safety

Caller must ensure that the raw body is a valid representation of T. If all bit patterns are valid representations of T then this is always safe but the result might still be nonsense.

pub unsafe fn body_as_unchecked<T>(&self) -> &T

Returns a reference to the body interpreted as type T without checking whether the header’s indicated length is long enough for that type.

Safety

Caller must ensure that there’s enough valid memory after the event header for a T and that the data there is a valid representation of T.
