Trait ToColumn 

pub trait ToColumn {
    // Required method
    fn to_value(&self) -> Value;
}

Lowers a field value to a sea_query::Value for binding.

Impl’d explicitly (not via a blanket impl<T: Into<Value>>) for each supported type and its Option. The blanket form is tempting but is a coherence trap: it claims every T, so a downstream crate could never add ToColumn for its own enum/newtype. Keeping these concrete leaves the trait open — a custom column type adds one ToColumn impl (see impl_string_column! for the string-enum case).

Required Methods

fn to_value(&self) -> Value

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".

impl<T: ToColumn + SqlType> ToColumn for Option<T>

Blanket nullability for binding, mirroring the FromColumn side: None binds as a typed NULL chosen from the inner type’s ColumnType (some drivers need the type even for NULL), Some delegates. Coherent in-crate, so custom types are nullable without a downstream Option impl.
