Struct Expression 

#[non_exhaustive]
pub struct Expression {
    pub or: Option<Vec<Expression>>,
    pub and: Option<Vec<Expression>>,
    pub not: Option<Box<Expression>>,
    pub dimensions: Option<DimensionValues>,
    pub tags: Option<TagValues>,
    pub cost_categories: Option<CostCategoryValues>,
}

Defines complex filtering conditions using logical operators (AND, OR, NOT) and various filter types.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

or: Option<Vec<Expression>>

A list of expressions to combine with OR logic.

and: Option<Vec<Expression>>

A list of expressions to combine with AND logic.

not: Option<Box<Expression>>

An expression to negate with NOT logic.

dimensions: Option<DimensionValues>

The dimension values to include in the filter expression.

tags: Option<TagValues>

The tag values to include in the filter expression.

cost_categories: Option<CostCategoryValues>

The cost category values to include in the filter expression.

Implementations

impl Expression

pub fn or(&self) -> &[Expression]

A list of expressions to combine with OR logic.

If no value was sent for this field, a default will be set. If you want to determine if no value was sent, use .or.is_none().

pub fn and(&self) -> &[Expression]

A list of expressions to combine with AND logic.

If no value was sent for this field, a default will be set. If you want to determine if no value was sent, use .and.is_none().

pub fn not(&self) -> Option<&Expression>

An expression to negate with NOT logic.

pub fn dimensions(&self) -> Option<&DimensionValues>

The dimension values to include in the filter expression.

pub fn tags(&self) -> Option<&TagValues>

The tag values to include in the filter expression.

pub fn cost_categories(&self) -> Option<&CostCategoryValues>

The cost category values to include in the filter expression.

impl Expression

pub fn builder() -> ExpressionBuilder

Creates a new builder-style object to manufacture Expression.

Trait Implementations

impl Clone for Expression

fn clone(&self) -> Expression

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Expression

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

Formats the value using the given formatter.

impl PartialEq for Expression

fn eq(&self, other: &Expression) -> 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.
