Struct RPartialOrdView 

#[repr(C)]
pub struct RPartialOrdView {
    pub data: *mut c_void,
    pub vtable: *const RPartialOrdVTable,
}

Runtime view for objects implementing RPartialOrd. Generated from source location line 204, column 11. Generated from source file miniextendr-api/src/adapter_traits.rs.

Combines a data pointer with a vtable pointer for method dispatch. Use try_from_sexp to create a view from an R external pointer.

Fields

data: *mut c_void

Pointer to the concrete object data.

vtable: *const RPartialOrdVTable

Pointer to the vtable for this trait.

Implementations

impl RPartialOrdView

pub unsafe fn try_from_sexp(sexp: SEXP) -> Option<Self>

Try to create a view from an R SEXP.

Returns Some(Self) if the object implements this trait, None otherwise.

Safety

• sexp must be a valid R external pointer (EXTPTRSXP)
• Must be called on R’s main thread

pub unsafe fn from_sexp(sexp: SEXP) -> Self

Try to create a view, panicking with error message on failure.

Safety

Same as try_from_sexp.

unsafe fn from_raw_parts(data: *mut c_void, vtable: *const c_void) -> Self
