Struct ExprStartsWith 

pub struct ExprStartsWith {
    pub expr: Box<Expr>,
    pub prefix: Box<Expr>,
}

A string prefix-match expression: starts_with(expr, prefix).

Returns true if expr starts with prefix. The attribute reference is always expr (lhs) and the prefix value is always prefix (rhs).

Examples

starts_with(name, "Al")   // true if name starts with "Al"

Fields

expr: Box<Expr>

The attribute to test.

prefix: Box<Expr>

The prefix value to match against.

Trait Implementations

impl Clone for ExprStartsWith

fn clone(&self) -> ExprStartsWith

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ExprStartsWith

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

Formats the value using the given formatter.

impl From<ExprStartsWith> for Expr

fn from(value: ExprStartsWith) -> Self

Converts to this type from the input type.

impl PartialEq for ExprStartsWith

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