Enum Level 

#[non_exhaustive]
#[repr(u8)]
pub enum Level {
    None = 0,
    Note = 1,
    Help = 2,
    Warning = 3,
    Error = 4,
}

Diagnostic severity level, ordered from least to most severe.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

None = 0

No diagnostic (default). Not emitted.

Note = 1

Informational note.

Help = 2

Helpful suggestion.

Warning = 3

Compiler warning.

Error = 4

Hard compile error.

Implementations

impl Level

pub fn to_u8(&self) -> u8

Returns the numeric value of this level.

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

Returns a lowercase string representation ("error", "warning", etc.).

Trait Implementations

impl Clone for Level

fn clone(&self) -> Level

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Level

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

Formats the value using the given formatter.

impl Default for Level

fn default() -> Level

Returns the “default value” for a type.

impl Display for Level

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

Formats the value using the given formatter.

impl From<Level> for Level

Available on crate feature diagnostics only.

fn from(value: Level) -> Self

Converts to this type from the input type.

impl From<Level> for Level

Available on crate feature diagnostics only.

fn from(value: Level) -> Self

Converts to this type from the input type.

impl Ord for Level

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

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

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