Struct RuleStringExpression 

#[non_exhaustive]
pub struct RuleStringExpression {
    pub evaluate: Option<RuleStringToEvaluate>,
    pub operator: RuleStringOperator,
    pub values: Vec<String>,
}

A string expression is evaluated against strings or substrings of the email.

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.

evaluate: Option<RuleStringToEvaluate>

The string to evaluate in a string condition expression.

operator: RuleStringOperator

The matching operator for a string condition expression.

values: Vec<String>

The string(s) to be evaluated in a string condition expression. For all operators, except for NOT_EQUALS, if multiple values are given, the values are processed as an OR. That is, if any of the values match the email's string using the given operator, the condition is deemed to match. However, for NOT_EQUALS, the condition is only deemed to match if none of the given strings match the email's string.

Implementations

impl RuleStringExpression

pub fn evaluate(&self) -> Option<&RuleStringToEvaluate>

The string to evaluate in a string condition expression.

pub fn operator(&self) -> &RuleStringOperator

The matching operator for a string condition expression.

pub fn values(&self) -> &[String]

The string(s) to be evaluated in a string condition expression. For all operators, except for NOT_EQUALS, if multiple values are given, the values are processed as an OR. That is, if any of the values match the email's string using the given operator, the condition is deemed to match. However, for NOT_EQUALS, the condition is only deemed to match if none of the given strings match the email's string.

impl RuleStringExpression

pub fn builder() -> RuleStringExpressionBuilder

Creates a new builder-style object to manufacture RuleStringExpression.

Trait Implementations

impl Clone for RuleStringExpression

fn clone(&self) -> RuleStringExpression

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RuleStringExpression

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

Formats the value using the given formatter.

impl PartialEq for RuleStringExpression

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