Struct InheritanceInfo 

pub struct InheritanceInfo {
    pub strategy: InheritanceStrategy,
    pub parent: Option<&'static str>,
    pub discriminator_column: Option<&'static str>,
    pub discriminator_value: Option<&'static str>,
}

Inheritance metadata for a model.

This struct captures the inheritance configuration for models that participate in table inheritance hierarchies.

Fields

strategy: InheritanceStrategy

The inheritance strategy for this model.

parent: Option<&'static str>

The parent model name (for child models).

When set, this model inherits from the specified parent model.

discriminator_column: Option<&'static str>

The discriminator column name (for single table inheritance base models).

For single table inheritance, this specifies which column contains the type discriminator values that distinguish between different model types.

discriminator_value: Option<&'static str>

The discriminator value for this model (single table inheritance child).

For single table inheritance, this value is stored in the discriminator column to identify rows belonging to this specific model type.

Implementations

impl InheritanceInfo

pub const fn none() -> Self

Create a new InheritanceInfo with no inheritance.

pub const fn single_table() -> Self

pub const fn with_discriminator_column(self, column: &'static str) -> Self

Set the discriminator column name (builder pattern, for base models).

pub const fn with_discriminator_value(self, value: &'static str) -> Self
