Enum Dialect 

pub enum Dialect {
    Normative,
    ZeroTolerant,
    OneTolerant,
}

Dialect for ODO min_count interpretation

The dialect lever controls how min_count is interpreted for ODO arrays:

Dialect	min_count Interpretation	Description
Normative	min_count is enforced	Counter must be ≥ min_count (strict)
ZeroTolerant	min_count is ignored	Counter can be 0..max_count (relaxed)
OneTolerant	min_count clamped to 1	Counter must be ≥ max(1, min_count)

Examples

use copybook_dialect::Dialect;
use std::str::FromStr;

// Default dialect is Normative
let default = Dialect::default();
assert_eq!(default, Dialect::Normative);

// Parse from string
let normative = Dialect::from_str("n").unwrap();
assert_eq!(normative, Dialect::Normative);

let zero_tolerant = Dialect::from_str("0").unwrap();
assert_eq!(zero_tolerant, Dialect::ZeroTolerant);

let one_tolerant = Dialect::from_str("1").unwrap();
assert_eq!(one_tolerant, Dialect::OneTolerant);

Variants

Normative

Normative dialect - min_count is strictly enforced

Counter must be ≥ min_count. This is the default behavior.

ZeroTolerant

Zero-tolerant dialect - min_count is ignored

Counter can be 0..max_count, regardless of declared min_count.

OneTolerant

One-tolerant dialect - min_count is clamped to 1

Counter must be ≥ max(1, min_count). This allows zero-length arrays when min_count is 0, but enforces at least one element otherwise.

Trait Implementations

impl Clone for Dialect

fn clone(&self) -> Dialect

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Dialect

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

Formats the value using the given formatter.

impl Default for Dialect

fn default() -> Dialect

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Dialect

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for Dialect

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

Formats the value using the given formatter.

impl FromStr for Dialect

type Err = String

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Self, Self::Err>

Parses a string s to return a value of this type.

impl Hash for Dialect

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for Dialect

fn eq(&self, other: &Dialect) -> 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.

impl Serialize for Dialect

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Copy for Dialect
