Struct QueryVariable 

pub struct QueryVariable(/* private fields */);

Validated canonical query-variable spelling without a $ sigil.

Implementations

impl QueryVariable

pub fn new(value: impl Into<String>) -> Result<Self, Diagnostic>

Validate a bounded lowercase variable spelling.

pub fn as_str(&self) -> &str

Return the canonical spelling.

impl Ord for QueryVariable

fn cmp(&self, other: &QueryVariable) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

fn clamp_to<R>(self, range: R) -> Self

where Self: Sized, R: ClampBounds<Self>,

🔬This is a nightly-only experimental API. (clamp_to)

Restrict a value to a certain range.

impl PartialEq for QueryVariable

fn eq(&self, other: &QueryVariable) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.

impl PartialOrd for QueryVariable

fn partial_cmp(&self, other: &QueryVariable) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool
