Struct TypeOverride 

pub struct TypeOverride {
    pub column: Option<String>,
    pub db_type: Option<String>,
    pub neutral_type: Option<String>,
}

A type override that replaces the inferred neutral type for a column or SQL type.

Overrides are evaluated in order: the first match wins. A column match (e.g. "users.metadata") takes priority over a db_type match when both fields are set on the same override entry, but a column that fails to match falls through to db_type on the same entry rather than making the whole entry a no-op (#189) – the two predicates degrade independently, they don’t gate each other.

Fields

column: Option<String>

Fully-qualified column reference in "table.column" format.

db_type: Option<String>

SQL type name (matched case-insensitively against the column’s neutral type).

neutral_type: Option<String>

Target neutral type to substitute (e.g. "string", "json").

Implementations

impl TypeOverride

pub fn matches(&self, column_match: &str, col_neutral_type: &str) -> bool

Check if this override matches a column.

column_match is "table_name.column_name" (empty string if unknown). col_neutral_type is the neutral type inferred by the analyzer.

Trait Implementations

impl Clone for TypeOverride

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for TypeOverride

fn fmt(&self, f: &mut Formatter<'_>) -> Result
