Trait EncodeColumn

    // Required methods
    fn column_type(&self) -> &str;
    fn encode_value<'a>(&self, value: Option<&'a JsonValue>) -> Cow<'a, str>;

}

Encodes the column to be sent to the database.

Required Methods

fn column_type(&self) -> &str

Returns the corresponding column type in the database.

fn encode_value<'a>(&self, value: Option<&'a JsonValue>) -> Cow<'a, str>

Encodes a json value as a column value represented by a str.

fn format_value<'a>(&self, value: &'a str) -> Cow<'a, str>

Formats a string value for the column.

fn format_filter(&self, key: &str, value: &JsonValue) -> String

Formats a column filter.
