Struct RCell 

#[repr(C)]
pub struct RCell {
    pub kind: RCellKind,
    pub text: Option<String>,
    pub number: f64,
    pub bytes: u64,
}

FFI-safe mirror of Cell — a single cell in a Table reading. Three parallel payload fields; the active one is selected by kind. Inactive fields carry default values that are never read.

Fields

kind: RCellKind

text: Option<String>

number: f64

bytes: u64

Implementations

impl RCell

where Struct<FieldPair<FieldPair<FieldPair<RCellKind, Option<String>>, f64>, u64>>: IStable, u64: IStable, f64: IStable, Option<String>: IStable, RCellKind: IStable,

pub const fn has_optimal_layout() -> bool

Returns true if the layout for RCell is smaller or equal to that Rust would have generated for it.

Trait Implementations

impl Clone for RCell

fn clone(&self) -> RCell

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RCell

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

Formats the value using the given formatter.

impl From<Cell> for RCell

fn from(c: Cell) -> Self

Converts to this type from the input type.

impl From<RCell> for Cell

fn from(r: RCell) -> Self

Converts to this type from the input type.

impl IStable for RCell

where Struct<FieldPair<FieldPair<FieldPair<RCellKind, Option<String>>, f64>, u64>>: IStable, u64: IStable, f64: IStable, Option<String>: IStable, RCellKind: IStable,

const REPORT: &'static TypeReport

A compile-time generated report of the fields of the type, allowing for compatibility inspection.

const ID: u64

A stable (and ideally unique) identifier for the type. Often generated using crate::report::gen_id, but can be manually set.

type ForbiddenValues = <Struct<FieldPair<FieldPair<FieldPair<RCellKind, Option<String>>, f64>, u64>> as IStable>::ForbiddenValues

The values that the annotated type cannot occupy.

type UnusedBits = <Struct<FieldPair<FieldPair<FieldPair<RCellKind, Option<String>>, f64>, u64>> as IStable>::UnusedBits

The padding bits in the annotated types

type Size = <Struct<FieldPair<FieldPair<FieldPair<RCellKind, Option<String>>, f64>, u64>> as IStable>::Size

The size of the annotated type in bytes.

type Align = <Struct<FieldPair<FieldPair<FieldPair<RCellKind, Option<String>>, f64>, u64>> as IStable>::Align

The alignment of the annotated type in bytes.

type HasExactlyOneNiche = <Struct<FieldPair<FieldPair<FieldPair<RCellKind, Option<String>>, f64>, u64>> as IStable>::HasExactlyOneNiche

Allows the detection of whether or not core::option::Options are stable:

type ContainsIndirections = <Struct<FieldPair<FieldPair<FieldPair<RCellKind, Option<String>>, f64>, u64>> as IStable>::ContainsIndirections

Whether or not the type contains indirections (pointers, indices in independent data-structures…)

fn size() -> usize

Returns the size of the type.

fn align() -> usize

Returns the alignment of the type.

unsafe fn is_invalid(ptr: *const u8) -> bool

Returns true if ptr points to memory that cannot be a valid value of Self.
