Struct ContentFacts 

pub(crate) struct ContentFacts {
    pub initialized: bool,
    pub cstr_trusted: bool,
    pub utf8_trusted: bool,
}

Per-allocation content facts: whether the allocation’s contents are readable, and whether they were asserted to be a valid C string / UTF-8. These describe the stored bytes/values, so they live on MemoryContent next to that data, rather than on AllocFacts (lifecycle).

Fields

initialized: bool

Whether the allocation’s contents hold an initialized (readable) value: a heap constructor (Box::new, Vec), a reference parameter’s referent, a callee return, a write, ValidCStr, or const/static byte data. Stays false for uninitialized memory (Box::new_uninit, MaybeUninit::uninit).

cstr_trusted: bool

Whether this allocation was asserted valid C string via a ValidCStr contract fact / struct invariant (the “no interior NUL + terminal NUL” trust marker).

utf8_trusted: bool

Whether this allocation was asserted valid UTF-8 via a ValidString contract fact (the “bytes form a valid UTF-8 sequence” trust marker).

impl Default for ContentFacts

fn default() -> Self
