Enum Level 

pub enum Level {
    Info,
    Warning,
    Error,
}

Error level for a diagnostic message.

Variants

Info

Level used for diagnostics that don’t point out anything wrong with the plan, and merely provide additional information.

Warning

Level used for diagnostics that may or may not indicate that there is something wrong with the plan, i.e. the plan could be valid, but the validator isn’t sure.

Error

Level used for diagnostics that indicate that there is definitely something wrong with the plan.

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 From<&Level> for i32

fn from(node: &Level) -> Self

Converts to this type from the input type.

impl From<Level> for Validity

fn from(level: Level) -> Self

Converts to this type from the input type.

impl From<Validity> for Level

fn from(validity: Validity) -> 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.
