}

A single assertion tracking slot in shared memory.

All fields are accessed via raw pointer arithmetic on MAP_SHARED memory.

Fields

msg_hash: u32

FNV-1a hash of the assertion message (u32).

kind: u8

The kind of assertion (AssertKind as u8).

must_hit: u8

Whether this assertion must be hit (1) or not (0).

maximize: u8

Whether to maximize (1) or minimize (0) the watermark value.

split_triggered: u8

Whether a fork has been triggered for this assertion (0 = no, 1 = yes).

pass_count: u64

Total number of times this assertion passed.

fail_count: u64

Total number of times this assertion failed.

watermark: i64

Numeric watermark: best value observed (for guidance assertions).

split_watermark: i64

Watermark value at last fork (for detecting improvement).

frontier: u8

Frontier: number of simultaneously true bools (for BooleanSometimesAll).

_pad: [u8; 7]

Padding for alignment.

msg: [u8; 64]

Assertion message string (null-terminated).

Implementations

impl AssertionSlot

pub fn msg_str(&self) -> &str

Get the assertion message as a string slice.
