Struct ErrTreePkg

pub struct ErrTreePkg { /* private fields */ }

Captures extra information for ErrTree automatically.

Self::new() must be called by a function annotated with #[track_caller] to capture the correct callsite.

The inner fields are obscured to allow arbitrary metadata tracking combinations via feature flags without changing the API. The boxed feature can be enabled to store this in heap.

All instances of this are considered equal, to avoid infecting sort order or comparisons between the parent error types. Hashing is a no-op.

Implementations

impl ErrTreePkg

pub fn new() -> Self

Trait Implementations

impl Clone for ErrTreePkg

fn clone(&self) -> ErrTreePkg

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ErrTreePkg

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

Formats the value using the given formatter.

impl Default for ErrTreePkg

fn default() -> Self

Returns the “default value” for a type.

impl Hash for ErrTreePkg

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 ErrTreePkg

fn cmp(&self, _other: &Self) -> 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 ErrTreePkg

fn eq(&self, _other: &Self) -> 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 ErrTreePkg

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