F64Col

umbral_core::orm::column

Struct F64Col 

Source 
pub struct F64Col<T> { /* private fields */ }
Expand description

A 64-bit float column (f64). Also serves f32 field declarations because f32 -> f64 is lossless; the SqlType variant on FieldSpec keeps the original precision distinction (Real vs Double) so the migration engine renders the right SQL column type.
