Struct FixedTickScheme 

pub struct FixedTickScheme { /* private fields */ }

Fixed price grid with an exact, positive tick size.

Navigation returns None if the requested output precision cannot represent the tick exactly.

Implementations

impl FixedTickScheme

pub fn new(tick: Price) -> Result<Self, TickSchemeError>

Creates a new FixedTickScheme with the given tick size.

Errors

Returns an error if the tick is not positive, is outside the representable price range, has invalid precision, or contains fractional digits beyond its precision.

pub fn new_with_precision( tick: Price, price_precision: u8, ) -> Result<Self, TickSchemeError>

Creates a fixed tick scheme with an explicit default output precision.

Errors

Returns an error if the tick is invalid, the output precision is invalid, or the tick is not exactly representable at that precision.

pub const fn tick(&self) -> Price

Returns the fixed tick size.

pub const fn precision(&self) -> u8

Returns the default output price precision.
