Enum Severity 

pub enum Severity {
    Error,
    Warning,
    Note,
}

How seriously a diagnostic should be taken.

The three are ordered by what they ask of a reader. An error is a program the toolchain refuses. A warning is a program it accepts and doubts, so cove check --deny-warnings refuses it instead. A note is a program it accepts and does not doubt: the compiler is saying what it deliberately did not prove, which is a fact about the language rather than a suspicion about this program, so no strictness setting turns one into a failure.

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 Display for Severity

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

impl Eq for Severity

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.
