Enum DiagnosticLevel 

pub enum DiagnosticLevel {
    Error,
    Warning,
    Allowed,
}

Diagnostic levels describe the severity of a diagnostic, and how the compiler should react to their emission.

Variants

Error

Diagnostics with the Error level will be emitted and will cause compilation to fail with a non-zero exit code.

Warning

Diagnostics with the Warning level will be emitted, but will not influence the exit code of the compiler.

Allowed

Diagnostics with the Allowed level will be suppressed and will not emit any message.

Trait Implementations

impl Clone for DiagnosticLevel

fn clone(&self) -> DiagnosticLevel

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DiagnosticLevel

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

Formats the value using the given formatter.

impl Hash for DiagnosticLevel

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 Ord for DiagnosticLevel

fn cmp(&self, other: &DiagnosticLevel) -> 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 DiagnosticLevel

fn eq(&self, other: &DiagnosticLevel) -> 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 DiagnosticLevel

fn partial_cmp(&self, other: &DiagnosticLevel) -> 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.
