Struct Quantity 

pub struct Quantity { /* private fields */ }

Resolved order/trigger base quantity (protobuf qty_scaled).

Fields are private so metadata cannot be changed independently of the validated scaled value. Use the immutable metadata getters to inspect it.

Implementations

impl Quantity

pub fn from_scaled( scaled: i64, scale: Option<u32>, domain: QuantityDomain, symbol: Option<String>, symbol_id: Option<u32>, ) -> Result<Self>

pub fn from_decimal_str( raw: &str, scale: u32, symbol: Option<String>, symbol_id: Option<u32>, ) -> Result<Self>

pub fn from_decimal( raw: Decimal, scale: u32, symbol: Option<String>, symbol_id: Option<u32>, ) -> Result<Self>

pub fn from_quote_scaled( scaled: i64, scale: u32, symbol: Option<String>, symbol_id: Option<u32>, ) -> Result<Self>

Construct a quote-debit budget from scaled integer units.

scale is required so a bare integer can never silently inherit the catalog scale. Use crate::catalogs::Manager::quote_quantity_scale_for_symbol.

pub fn from_quote_decimal_str( raw: &str, scale: u32, symbol: Option<String>, symbol_id: Option<u32>, ) -> Result<Self>

pub fn from_quote_decimal( raw: Decimal, scale: u32, symbol: Option<String>, symbol_id: Option<u32>, ) -> Result<Self>

pub fn as_scaled(&self) -> i64

pub fn scale(&self) -> Option<u32>

pub fn domain(&self) -> QuantityDomain

pub fn symbol(&self) -> Option<&str>

pub fn symbol_id(&self) -> Option<u32>

pub fn format(&self, scale: Option<u32>) -> Result<String>

pub fn compatible_with( &self, domain: QuantityDomain, scale: Option<u32>, symbol: Option<&str>, symbol_id: Option<u32>, ) -> Result<()>
