Struct FailureDumpArrayEntry 

#[non_exhaustive]
pub struct FailureDumpArrayEntry {
    pub key: u32,
    pub value: Option<RenderedValue>,
}

One entry of a multi-entry BPF_MAP_TYPE_ARRAY map: the array key (u32) and its rendered value. Mirrors FailureDumpPercpuEntry’s typed u32 key (ARRAY keys are kernel-imposed indices, not user-typed bytes) but carries a single value rather than a per-CPU vector.

value is None only when the entry’s guest page was unmapped at the freeze instant; a BTF-render miss falls back to RenderedValue::Bytes (hex), so None unambiguously means “unreadable”, not “un-rendered”. ARRAY values are not sdt_data-arena-chased — no in-tree sched_ext ARRAY stores arena pointers; add a payload field here if one ever does.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

key: u32

Array index (kernel key).

value: Option<RenderedValue>

Rendered value (BTF when btf_value_type_id is non-zero, hex fallback otherwise). None when the entry was unreadable.

Trait Implementations

impl Clone for FailureDumpArrayEntry

fn clone(&self) -> FailureDumpArrayEntry

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for FailureDumpArrayEntry

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

Formats the value using the given formatter.

impl Default for FailureDumpArrayEntry

fn default() -> FailureDumpArrayEntry

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for FailureDumpArrayEntry

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for FailureDumpArrayEntry

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

key <N>: <rendered value> — one line for a flat struct, the value’s own multi-line body indented one level (depth=1) for a nested struct/array. <unreadable> marks a key whose guest page was unmapped at the freeze instant.

impl Serialize for FailureDumpArrayEntry

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
