Enum Bias 

pub enum Bias {
    GreatestLowerBound,
    LeastUpperBound,
}

Search bias for position lookups.

Controls how non-exact matches are resolved during binary search:

• GreatestLowerBound (default): find the closest mapping at or before the position
• LeastUpperBound: find the closest mapping at or after the position

Variants

GreatestLowerBound

Return the closest position at or before the requested position (default).

LeastUpperBound

Return the closest position at or after the requested position.

Trait Implementations

impl Clone for Bias

fn clone(&self) -> Bias

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Bias

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

Formats the value using the given formatter.

impl Default for Bias

fn default() -> Bias

Returns the “default value” for a type.

impl PartialEq for Bias

fn eq(&self, other: &Bias) -> 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 Copy for Bias

impl Eq for Bias

impl StructuralPartialEq for Bias
