#[repr(C)]
pub struct FFITypeConstraint {
    pub base_type: u8,
    pub constraint_type: u8,
    pub constraint_param1: u32,
    pub constraint_param2: u32,
}

FFI-safe representation of a TypeConstraint

Fields

base_type: u8

Base type code (Type::to_u8)

constraint_type: u8

Constraint type: 0=None, 1=MaxBytes, 2=PrecisionScale, 3=Dictionary, 4=SumType

constraint_param1: u32

First constraint param: MaxBytes value OR precision OR dictionary_id low 32 bits

constraint_param2: u32

Second constraint param: scale (PrecisionScale) OR id_type (Dictionary)

Trait Implementations

impl Clone for FFITypeConstraint

fn clone(&self) -> FFITypeConstraint

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FFITypeConstraint

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

Formats the value using the given formatter.

impl PartialEq for FFITypeConstraint

fn eq(&self, other: &FFITypeConstraint) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
