#[repr(u8)]
pub enum ReqLevel {
    Must = 0,
    Should = 1,
    May = 2,
}

RFC 2119 requirement level for a requirement.

See https://www.ietf.org/rfc/rfc2119.txt for the specification.

Variants

Must = 0

Absolute requirement (MUST, SHALL, REQUIRED)

Should = 1

Recommended but not required (SHOULD, RECOMMENDED)

May = 2

Truly optional (MAY, OPTIONAL)

Implementations

impl ReqLevel

pub fn parse(s: &str) -> Option<Self>

Parse a level from its string representation.

pub fn as_str(&self) -> &'static str

Get the string representation of this level.

Trait Implementations

impl Clone for ReqLevel

fn clone(&self) -> ReqLevel

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ReqLevel

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

Formats the value using the given formatter.

impl Default for ReqLevel

fn default() -> ReqLevel

Returns the “default value” for a type.

impl<'ʄ> Facet<'ʄ> for ReqLevel

const SHAPE: &'static Shape

The shape of this type, including: whether it’s a Struct, an Enum, something else?

impl Hash for ReqLevel

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,

impl PartialEq for ReqLevel

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