Enum DiagLevel 

pub enum DiagLevel {
    Off,
    Shape,
    ShapeTiming,
    ShapeRewriteDiff,
}

How much detail to record for a request (ordered: higher = more verbose).

Variants

Off

No recording/export beyond the always-on minimum. Near-zero cost.

Shape

Shape-only spans (ids, names, sizes), the standard causal trace.

ShapeTiming

Shapes plus per-stage timing.

ShapeRewriteDiff

Shapes, timing, and the rewrite before/after shape diff (never values).

Implementations

impl DiagLevel

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

The level’s stable wire name, the inverse of the publish/​header parser, so an introspected directive’s level re-publishes verbatim.

pub fn from_name(name: &str) -> Option<Self>

Parses a level’s wire name back to the level, the inverse of DiagLevel::as_str, so the publish/header/etcd vocabularies share one source of truth. None if the name is not a known level (fail-closed).

Trait Implementations

impl Clone for DiagLevel

fn clone(&self) -> DiagLevel

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for DiagLevel

impl Debug for DiagLevel

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

Formats the value using the given formatter.

impl Default for DiagLevel

fn default() -> DiagLevel

Returns the “default value” for a type.

impl Eq for DiagLevel

impl Ord for DiagLevel

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

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

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