Expand description

Represents a continuous interval over some data type that is used for keys.

Implementations

source

impl KeyRange

source

pub fn only(value: &JsValue) -> Result<Self, Error>

Returns a new KeyRange spanning only key.

source

pub fn bound(
 lower: &JsValue,
 upper: &JsValue,
 lower_open: Option<bool>,
 upper_open: Option<bool>
) -> Result<Self, Error>

Returns a new KeyRange spanning from lower to upper. If lower_open is true, lower is not included in the range. If upper_open is true, upper is not included in the range.

source

pub fn lower_bound(
lower: &JsValue,
lower_open: Option<bool>
) -> Result<Self, Error>

Returns a new KeyRange starting at key with no upper bound. If lower_open is true, key is not included in the range.

source

pub fn upper_bound(
upper: &JsValue,
upper_open: Option<bool>
) -> Result<Self, Error>

Returns a new KeyRange with no lower bound and ending at key. If upper_open is true, key is not included in the range.

source

pub fn lower(&self) -> Result<JsValue, Error>

Returns the range’s lower bound, or undefined if none.

source

pub fn upper(&self) -> Result<JsValue, Error>

Returns the range’s upper bound, or undefined if none.

source

pub fn lower_open(&self) -> bool

Returns the range’s lower open flag.

source

pub fn upper_open(&self) -> bool

Returns the range’s upper open flag.

source

pub fn includes(&self, value: &JsValue) -> Result<bool, Error>

Returns true if key is included in the range, and false otherwise.
