Struct ShadowTablePolicy 

pub struct ShadowTablePolicy {
    pub kind: ShadowTableKind,
    pub direct_dml: ShadowTableAccess,
    pub schema_ddl: ShadowTableAccess,
    pub module_internal_write: ShadowTableAccess,
}

Policy returned by a module when the core asks whether a table name is a shadow table of a virtual table instance.

Fields

kind: ShadowTableKind

Whether the table is ordinary or shadow-owned.

direct_dml: ShadowTableAccess

User-authored INSERT/UPDATE/DELETE against this schema object.

schema_ddl: ShadowTableAccess

User-authored schema changes such as CREATE TRIGGER on this object.

module_internal_write: ShadowTableAccess

Writes performed by the owning module while applying its own lifecycle.

Implementations

impl ShadowTablePolicy

pub const fn ordinary() -> Self

Policy for an ordinary, non-shadow table.

pub const fn owned_shadow() -> Self

Policy for a module-owned shadow table.

pub const fn is_shadow(self) -> bool

Whether the table is module-owned shadow state.

pub const fn allows_direct_dml(self) -> bool

Whether user-authored INSERT/UPDATE/DELETE should be accepted.

pub const fn allows_schema_ddl(self) -> bool

Whether user-authored schema DDL such as CREATE TRIGGER should be accepted.

pub const fn allows_module_internal_write(self) -> bool

Whether the owning module may write this object internally.

Trait Implementations

impl Clone for ShadowTablePolicy

fn clone(&self) -> ShadowTablePolicy

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ShadowTablePolicy

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

Formats the value using the given formatter.

impl Default for ShadowTablePolicy

fn default() -> Self

Returns the “default value” for a type.

impl PartialEq for ShadowTablePolicy

fn eq(&self, other: &ShadowTablePolicy) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
