Struct FieldExclusion 

pub struct FieldExclusion {
    pub name: Option<String>,
    pub index: Option<String>,
    pub value: Option<String>,
}

A Lace-130 exclusion: records carrying a matching Field occurrence.

None components are the anonymous _. The composer appends the negated atom to every composed selection and exposure facet, and its AdvertisedField counterpart to request selection.

Implementations

impl FieldExclusion

pub fn named(name: impl Into<String>) -> FieldExclusion

Exclude records carrying any occurrence of field name.

Trait Implementations

impl Clone for FieldExclusion

fn clone(&self) -> FieldExclusion

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FieldExclusion

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

Formats the value using the given formatter.

impl Default for FieldExclusion

fn default() -> FieldExclusion

Returns the “default value” for a type.

impl Eq for FieldExclusion

impl Hash for FieldExclusion

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

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 FieldExclusion

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

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

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