Enum Severity 

pub enum Severity {
    Unsafe,
    Unsurveyed,
    Coarse,
    Caution,
}

How much a finding matters.

Declaration order is the ranking, worst first: a danger outranks silence, silence outranks a coarse answer, and all three outrank an advisory. Unsurveyed and Coarse rank above Caution because they describe how far the check itself can be trusted, not a property of the water.

Variants

Unsafe

The vessel cannot pass here: land, water shallower than the safety contour, or a danger whose depth is unknown.

Unsurveyed

The chart has no coverage here. Reports an unanswered question, not clear water.

Coarse

There is data, but it was compiled at a scale too small to answer the question that was asked of it. A clear result here means “no danger was drawn at this scale”, which is a weaker statement than “there is no danger”.

Caution

Passable, but the mariner has to know: a restricted area, a traffic separation scheme, a cable field nobody should anchor in.

Trait Implementations

impl Clone for Severity

fn clone(&self) -> Severity

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Severity

impl Debug for Severity

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

Formats the value using the given formatter.

impl Eq for Severity

impl Ord for Severity

fn cmp(&self, other: &Severity) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for Severity

fn eq(&self, other: &Severity) -> 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 PartialOrd for Severity

fn partial_cmp(&self, other: &Severity) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
