Struct Range 

pub struct Range {
    pub flags: u8,
    pub lower: Value,
    pub upper: Value,
}

A value of a range type: the flags of rangetypes.h and the two bounds. A bound that is infinite is Value::Null, and so are both bounds of an empty range.

Fields

flags: u8

lower: Value

upper: Value

Implementations

impl Range

pub fn empty() -> Range

The empty range.

pub fn is_empty(&self) -> bool

True for an empty range.

pub fn has_lower(&self) -> bool

RANGE_HAS_LBOUND: the range has a lower bound value.

pub fn has_upper(&self) -> bool

RANGE_HAS_UBOUND: the range has an upper bound value.
