Struct QueryFilterCondition 

pub struct QueryFilterCondition {
    pub operator: QueryFilterOperator,
    pub value: Option<String>,
}

Represents a complete filter condition with operator and value(s).

This structure encapsulates a filtering operation, including the operator and the value(s) to compare against. It’s used internally to build type-safe SQL WHERE conditions.

Fields

operator: QueryFilterOperator

The comparison operator to use

value: Option<String>

The value(s) to compare against

• For most operators: single value (e.g., “10”, “active”)
• For IN/NOT IN: comma-separated values (e.g., “admin,moderator,user”)
• For IS NULL/IS NOT NULL: ignored (can be None)

Implementations

impl QueryFilterCondition

pub fn new( operator: QueryFilterOperator, value: Option<impl Into<String>>, ) -> Self

Creates a new filter condition.

Arguments

• operator - The comparison operator
• value - The value to compare against (None for IS NULL/IS NOT NULL)

pub fn equal(value: impl Into<String>) -> Self

Creates an equality filter condition.

pub fn not_equal(value: impl Into<String>) -> Self

Creates a not equal filter condition.

pub fn greater_than(value: impl Into<String>) -> Self

Creates a greater than filter condition.

pub fn greater_or_equal(value: impl Into<String>) -> Self

Creates a greater or equal filter condition.

pub fn less_than(value: impl Into<String>) -> Self

Creates a less than filter condition.

pub fn less_or_equal(value: impl Into<String>) -> Self

Creates a less or equal filter condition.

pub fn in_list(values: Vec<impl Into<String>>) -> Self

Creates an IN filter condition.

Arguments

• values - Vector of values to check against

pub fn not_in_list(values: Vec<impl Into<String>>) -> Self

Creates a NOT IN filter condition.

pub fn is_null() -> Self

Creates an IS NULL filter condition.

pub fn is_not_null() -> Self

Creates an IS NOT NULL filter condition.

pub fn like(pattern: impl Into<String>) -> Self

Creates a LIKE filter condition.

pub fn not_like(pattern: impl Into<String>) -> Self

Creates a NOT LIKE filter condition.

pub fn split_values(&self) -> Vec<String>

Splits the value into a vector for IN/NOT IN operations.
