macro_rules! col { ($viz:vis $name:ident : $ty:ty $(; $($derive:ident),*)?) => { ... }; }
Expand description
A macro to define a field.
The col!
macro defines a column type that will properly
interact with memquery
.
The inner type must be 'static
and cannot take any generic
parameters.
Most derivable traits in std
are automatically implemented
for the resulting type.
col!{ pub TestField: u32 }
