Struct VmOrigin 

pub struct VmOrigin {
    pub local: Local,
    pub alloc_id: AllocId,
    pub kind: VmOriginKind,
}

Information about a value’s ultimate origin.

Fields

local: Local

The local (parameter or stack variable) that is the root source.

alloc_id: AllocId

The allocation ID this pointer targets.

kind: VmOriginKind

The type of the origin local (Ref/MutRef/RawPtr/Adt/…).

Implementations

impl VmOrigin

pub fn is_mut_ref(&self) -> bool

Whether this origin is a &mut T reference — safe to create a unique view from.

pub fn is_shared_ref(&self) -> bool

Whether this origin is a &T reference — safe to create a shared view from.

pub fn is_owned(&self) -> bool

Whether this origin is an owned type (Box, Vec) whose allocation was transferred to this function.
