Struct DbOperationContext 

pub struct DbOperationContext {
    pub adapter: DbAdapterKind,
    pub operation: String,
    pub namespace: String,
    pub physical_key: Option<String>,
    pub result_shape: DbResultShape,
}

Diagnostic context for one database cache operation.

The context is deliberately database-neutral. It describes the cache-side operation and adapter helper while the database library keeps ownership of typed database errors, transactions, query construction, and row mapping.

Fields

adapter: DbAdapterKind

Adapter helper that initiated the operation.

operation: String

Diagnostic operation name.

namespace: String

Cache namespace used to build physical keys.

physical_key: Option<String>

Physical cache key when one was available.

result_shape: DbResultShape

Result shape requested by the caller or adapter helper.

Trait Implementations

impl Clone for DbOperationContext

fn clone(&self) -> DbOperationContext

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DbOperationContext

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

Formats the value using the given formatter.

impl Display for DbOperationContext

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

Formats the value using the given formatter.

impl Eq for DbOperationContext

impl PartialEq for DbOperationContext

fn eq(&self, other: &DbOperationContext) -> 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.
