Implementations

impl Expression

pub fn create_param(value: &str, params: &mut Vec<String>) -> String

pub fn evaluate( &self, record: &HashMap<String, String>, case_sensitive: bool, ) -> bool

Trait Implementations

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.

impl ToSql for Expression

fn to_sql(&self, options: SqlOptions) -> (String, Vec<String>)

fn to_sql_internal( &self, params: &mut Vec<String>, options: SqlOptions, ) -> String

impl StructuralPartialEq for Expression
